1. Introduction
The DSP-100 provides two independent RS-232 asynchronous serial
communications interfaces for systems equipped with PCMCIA Type II
and/or Type III expansion sockets. The DSP-100 is a PCMCIA Type II (5
mm) card and is PCMCIA PC Card Standard Specification 2.1 compliant.
The DSP-100's serial ports are implemented using 16C550 Universal
Asynchronous Receiver/Transmitters (UARTs) which are the
recommended communications interface for multitasking environments
and with applications involving high data transfer rates.
The DSP-100's two serial ports are addressable in two modes:
1. 'Block Mode': The two serial ports are configured in one
16-byte continuous block of I/O address space. The block must
begin on an even 16-byte division. Both serial ports share one
IRQ level.
2. 'COM Mode': The two serial ports are configured at the
standard COM port I/O address locations. The ports may be
configured as COM1 and COM3; also, the ports may be
configured as COM2 and COM4. Both serial ports share one
IRQ level.
A special interrupt status register is also available to simplify the software
required to service multiple serial ports in an interrupt driven
environments. See the Hardware Information section for details.

2. DOS / Windows 3.x Installation
Two configuration software programs are provided with the DSP-100: a
Client Driver, DSP100CL.SYS, and a card Enabler, DSP100EN.EXE. Both
of these programs are executed from DOS (before entering Windows) and
allow operation of the DSP-100 in both the DOS and Windows 3.x
environments. For optimal operation, however, the Client Driver is the
preferred method of installation and configuration. The table below
highlights the differences between these programs.

Card and Socket Services software is commercially available from several
vendors for most desktop and laptop PCs. If you are unsure whether
Card and Socket Services software is currently installed on your system,
install the DSP-100 Client Driver as discussed in following section. When
loaded, the Client Driver will display an error message if Card and Socket
Services software is not detected.
DSP-100 User’s Manual
2-1
2.1 DSP-100 Client Driver for DOS
In order to use the DSP-100 Client Driver, the system must be configured
with Card and Socket Services software. Card and Socket Services
software is not provided with the DSP-100 but is available from Omega.
IMPORTANT:
Some versions of Card and Socket Services dated before
1993 do not support general purpose I/O cards. If after
careful installation of the Client Driver the DSP-100 does
not configure or operate properly, an updated version of
Card and Socket Services may be required. Card and
Socket Services software is available from Omega Inc.
2.1.1 Client Driver Installation
The following procedure is used to install the DSP-100 Client Driver:
1. Copy the file DSP100CL.SYS from the DSP-100 distribution
diskette onto the system's hard drive.
2. Using an ASCII text editor, open the system's CONFIG.SYS file
located in the root directory of the boot drive.
3. Locate the line(s) in the CONFIG.SYS file where the Card and
Socket Services software is installed.
4. AFTER the line(s) installing the Card and Socket Services
software, add the following line to the CONFIG.SYS file:
DEVICE = drive:\path\DSP100CL.SYS options
where options are the DSP-100 Client Driver command line
options discussed on the following pages.
5. Save the CONFIG.SYS file and exit the text editor.
6. Insert the DSP-100 into one of the system's PCMCIA slots.
NOTE: Since the DSP-100 Client Driver supports "Hot Swapping",
it is not necessary to have the DSP-100 installed when booting the
system. By inserting the card before booting, however, the Client
Driver will report the adapter configuration during the boot
process thereby verifying the changes made to the CONFIG.SYS.
2-2
7. Reboot the system and note the message displayed when the
DSP-100 Client Driver is loaded. If the Client Driver reports an
"invalid command line option", correct the entry in the
CONFIG.SYS file and reboot the system again. If the Client
Driver reports "Card and Socket Services not found", a version
of Card and Socket Services must be installed on the system or
the DSP-100 Enabler program must be used to configure the
adapter. If the Client Driver reports the desired adapter
configuration, the installation process is complete and the
DSP-100 may be removed and / or inserted from the system as
desired. On each insertion into the PCMCIA socket, the
DSP-100 will be automatically reconfigured according to the
command line options.
2.1.2 Command Line Options
The DSP-100 Client Driver accepts up to eight command line arguments
from the user to determine the configuration of the DSP-100. If any
arguments are provided, the Client Driver will attempt to configure any
DSP-100s with the options specified in the order they are entered on the
command line. Each argument must be enclosed in parenthesis and must
be separated from other arguments by a space on the command line.
Within each argument, any or all of the following parameters may be
specified using a comma (no spaces) to separate each parameter:
Baddress
specifies a “block mode” base I/O address of the DSP-100 in
hexadecimal. This address must reside on an even 16-byte
(10H) boundary. This option must be omitted if using the
Dmode option. If both the Dmode and Baddress options are
omitted, a “block mode” base address will be assigned by
Card and Socket Services.
Dmode
specifies a “COM” mode” base I/O address configuration for
the DSP-100. The D1 option configures the DSP-100 at
COM1/COM3 (3F8 / 3E8), and the D2 option configures the
DSP-100 at COM2/COM4 (2F8 / 2E8). This option must be
omitted if using the Baddress option. If both the Dmode and
Baddress options are omitted, a “block mode” base address will
be assigned by Card and Socket Services.
Iirq
specifies the interrupt level (IRQ) of the DSP-100 in decimal.
irq must be one of the following values: 3, 4, 5, 7, 9, 10, 11, 12,
14, 15, or 0 if no IRQ is desired. If this option is omitted, an
interrupt level will be assigned by Card and Socket Services.
DSP-100 User’s Manual
2-3
Ssocket
specifies which PCMCIA socket the DSP-100 must be inserted
into for this configuration argument to be used. socket must be
in the range 0 - 15. If this option is omitted, the configuration
argument will apply to DSP-100s inserted into any socket.
U
instructs the Client Driver to disable the DSP-100's interrupt
status register and enable the Scratchpad registers of the
individual UARTs. This option is only required in very rare
cases where an application program requires access to the
UART's Scratchpad register. If this option is omitted, the
DSP-100's interrupt status register is enabled and the UARTs'
Scratchpad registers are disabled.
2.1.2.1 Example 1
DEVICE = C:\DSP-100\DSP100CL.SYS
In example 1, no command line arguments are specified. The Client
Driver will configure a DSP-100 inserted into any socket in “block mode”
with a base address and IRQ assigned by Card and Socket Services. The
DSP-100's interrupt status register will be enabled.
2.1.2.2 Example 2
DEVICE = C:\DSP-100\DSP100CL.SYS (d1)
In example 2, a single command line argument is provided. The Client
Driver will attempt to configure a DSP-100 inserted into any socket in
“COM mode” at COM1/COM3 and an IRQ assigned by Card and Socket
Services. If address COM1 (3F8) or COM3 (3E8) are unavailable, the
DSP-100 will not be configured. If the Client Driver can successfully
configure the DSP-100 its interrupt status register will be enabled.
2-4
2.1.2.3 Example 3
DEVICE = C:\DSP-100\DSP100CL.SYS (s0,b300,i5)
In example 3, a single command line argument is provided. The Client
Driver will attempt to configure a DSP-100 inserted into socket 0 with a
base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable,
the DSP-100 will not be configured. In addition, if a DSP-100 is inserted
into any other socket, it will not be configured. If the Client Driver can
successfully configure the DSP-100 its interrupt status register will be
enabled.
2.1.2.4 Example 4
DEVICE = C:\DSP-100\DSP100CL.SYS (i5,u,b300)
In example 4, a single command line argument is provided. Because the
parameter order is not significant, the Client Driver will attempt to
configure a DSP-100 inserted into any socket with a base address of 300H
and IRQ 5. If address 300H or IRQ 5 is unavailable, the DSP-100 will not
be configured. If the Client Driver can successfully configure the
DSP-100, its interrupt status register will be disabled (Scratchpad registers
enabled).
2.1.2.5 Example 5
DEVICE = C:\DSP-100\DSP100CL.SYS (b300,i5) (i10) ( )
In example 5, three command line arguments are provided. The Client
Driver will first attempt to configure a DSP-100 inserted into any socket
with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is
unavailable, the Client Driver will proceed to the second command line
argument and attempt to configure the card with a base address assigned
by Card and Socket Services and IRQ 10. If IRQ 10 is also unavailable, the
Client Driver will proceed to the third command line argument and
attempt to configure the DSP-100 with a base address and an IRQ
assigned by Card and Socket Services. If the DSP-100 is successfully
configured, its interrupt status register will be enabled.
DSP-100 User’s Manual
2-5
2.1.2.6 Example 6
DEVICE = C:\DSP-100\DSP100CL.SYS (b300,i5) ( ) (i10)
In example 6, the three command line arguments of example 5 have been
rearranged. The Client Driver will first attempt to configure a DSP-100
inserted into any socket with a base address of 300H and IRQ 5. If
address 300H or IRQ 5 is unavailable, the Client Driver will proceed to
the second command line argument and attempt to configure the card
with a base address and IRQ assigned by Card and Socket Services. Since
the second command line argument includes all available address and
IRQ resources, the third command line argument will never be reached by
the Client Driver. It is the user's responsibility to place the command line
arguments in a logical order.
2.1.2.7 Example 7
DEVICE = C:\DSP-100\DSP100CL.SYS (s0,b300,i5) (s1,b340,i10)
The type of configuration shown in example 7 may be desirable in
systems where more than one DSP-100 is to be installed. In this example,
the Client Driver will attempt to configure a DSP-100 inserted into socket
0 with a base address of 300H and IRQ 5. If the DSP-100 is inserted into
socket 1, the Client Driver will attempt to configure it with base address
340H and IRQ 10. This allows the user to force the DSP-100's address and
IRQ settings to be socket specific which may simplify cable connections
and software development. As in the previous examples, however, if the
requested address or interrupt resources are not available, the DSP-100
will not be configured.
2-6
2.1.3 Common Problems
Generic Client Drivers:
Many Card and Socket Services packages include a generic client driver
(or SuperClient) which configures standard I/O devices. If one of these
generic client drivers is installed, it may configure the DSP-100 causing
the DSP-100 client driver to fail installation. In these cases, the user
should do one of the following:
1. modify the operation of the generic client driver to disable the
configuration of modem/serial port cards. Consult the Card
and Socket Services documentation for availability and details
of this feature.
2. place the DSP-100 client driver before the generic client driver
in the CONFIG.SYS.
Available Resources:
One function of the Card and Socket Services software is to track which
system resources (memory addresses, I/O addresses, IRQs, etc.) are
available for assignment to inserted PCMCIA cards. Sometimes,
however, the Card Services software assumes or incorrectly determines
that a particular resource is used when it is actually available. Most Card
and Socket Services generate a resource table in a file (typically in the
form of an .INI file) which the user can modify to adjust the available
system resources. Consult the Card and Socket Services documentation
for availability and details of this feature.
Multiple Configuration Attempts:
Some Card and Socket Services have a setting which aborts the
configuration process after a single configuration failure (such as a
request for an unavailable resource). The user should change this setting
to allow for multiple configuration attempts. Consult the Card and Socket
Services documentation for availability and details of this feature.
Older Versions of Card and Socket Services:
Some versions of Card and Socket Services dated before 1993 do not
support general purpose I/O cards. If after careful installation of the
Client Driver the DSP-100 does not configure or operate properly, an
updated version of Card and Socket Services may be required. Card and
Socket Services software is available from Omega.
DSP-100 User’s Manual

2.2 DSP-100 Enabler for DOS
For systems that are not operating PCMCIA Card and Socket Services
software, the DSP-100 DOS Enabler may be used to enable and configure
the adapter. This Enabler, DSP100EN.EXE, will operate on any DOS
system using an Intel 82365SL or PCIC compatible PCMCIA host adapter
including the Cirrus Logic CL-PD6710 / 6720, the VLSI VL82C146, and
the Vadem VG-365 among others.
IMPORTANT:
In order to use the DSP-100 Enabler for DOS, the system
MUST NOT be configured with Card and Socket Services
software. If a Card and Socket Services software is installed,
the DSP-100 Enabler may interfere with its operation and
with the device(s) it controls.
The DSP-100 Enabler does not support automatic configuration of
adapters upon insertion, more commonly referred to as "Hot Swapping".
This means the adapter must be installed in one of the system's PCMCIA
sockets before executing DSP100EN.EXE. If more than one adapter is
installed in a system, the Enabler must be executed separately for each
adapter. Furthermore, DSP100EN.EXE should be executed to release the
resources used by the adapter before it is removed from the PCMCIA
socket. Since PCMCIA adapters do not retain their configuration after
removal, any adapter that is removed from the system must be
reconfigured with the Enabler after re-inserting it into a PCMCIA socket.
IMPORTANT:
The Enabler requires a region of high DOS memory when
configuring a DSP-100. This region is 1000H bytes (4KB) long
and by default begins at address D0000H (the default address
may be changed using the "W" option). If a memory manager
such as EMM386, QEMM, or 386Max is installed on the system,
this region of DOS memory must be excluded from the memory
manager's control. Consult the documentation provided with
the memory manager software for instructions on how to
exclude this memory region.
2-8
2.2.1 Command Line Options
To configure a DSP-100 in the system, the Enabler requires one command
line argument from the user to determine the configuration of the card.
This argument must be enclosed in parenthesis and within the argument,
any or all of the following parameters may be specified using a comma
(no spaces) to separate each parameter:
Ssocket
specifies which PCMCIA socket the DSP-100 must be inserted
into for this configuration argument to be used. socket must be
in the range 0 - 15. This option is always required.
Baddress
specifies a “block mode” base I/O address of the DSP-100 in
hexadecimal. This address must reside on an even 16-byte
(10H) boundary. Specify only one of the following three
options: Baddress, Dmode, or ‘R’. Use of one of these options is
always required.
Dmode
specifies a “COM” mode” base I/O address configuration for
the DSP-100. The ‘D1’ option configures the DSP-100 at
COM1/COM3 (3F8 / 3E8), and the ‘D2’ option configures the
DSP-100 at COM2/COM4 (2F8 / 2E8). Specify only one of the
following three options: Baddress, Dmode, or ‘R’. Use of one of
these options is always required.
Iirq
specifies the interrupt level (IRQ) of the DSP-100 in decimal.
irq must be one of the following values: 3, 4, 5, 7, 9, 10, 11, 12,
14, 15, or 0 if no IRQ is desired. This option is required if the
'R' option is not used.
Waddress specifies the base address of the memory window required to
configure the DSP-100. Set address = D0 for a memory window
at segment D000, address = D8 for a memory window at
segment D800, etc. Valid settings for address are C8, CC, D0,
D4, D8, and DC. If this option is omitted, a memory window
at segment D000 will be used.
U
instructs the Enabler to disable the DSP-100's interrupt status
register and enable the Scratchpad registers of the individual
UARTs. This option is only required in very rare cases where
an application program requires access to the UART's
Scratchpad register. If this option is omitted, the DSP-100's
interrupt status register is enabled and the UARTs' Scratchpad
registers are disabled.
DSP-100 User’s Manual
2-9
Before removing a DSP-100 from its PCMCIA socket, the Enabler should
be executed to free the system resources allocated when the card was
installed. For this operation the Enabler provides on additional command
line option:
R
instructs the Enabler to release the resources previously
allocated to the DSP-100. When the 'R' option is used, any
settings specified by the 'B', 'I', and 'U' options are ignored.
2.2.1.1 Example 1
DSP100EN.EXE
In example 1, no command line argument is specified. The Enabler will
report an error and display the proper usage of the command.
2.2.1.2 Example 2
DSP100EN.EXE (s0,b300,i5)
In example 2, the Enabler will configure the DSP-100 in socket 0 with a
base address of 300H and IRQ 5 using a configuration memory window at
segment D000. The DSP-100's interrupt status register will be enabled.
2.2.1.3 Example 3
DSP100EN.EXE (i10,u,b340,s1)
In example 3, the Enabler will configure the DSP-100 in socket 1 with a
base address of 340H and IRQ 10 using a configuration memory window
at segment D000. The DSP-100's interrupt status register will be disabled
(Scratchpad registers enabled). Note that the parameter order is not
significant.
2-10
2.2.1.4 Example 4
DSP100EN.EXE (s0,b300,i3,wd8)
In example 4, the Enabler will configure the DSP-100 in socket 0 with a
base address of 300H and IRQ 3 using a configuration memory window at
segment D800. The DSP-100's interrupt status register will be enabled.
2.2.1.5 Example 5
DSP100EN.EXE (s0,b300,i5,r)
In example 5, the Enabler will release the configuration used by the
DSP-100 in socket 0 using a configuration memory window at segment
D000. The base address and IRQ parameters are ignored and may be
omitted.
2.2.1.6 Example 6
DSP100EN.EXE (s1,r,wcc)
In example 5, the Enabler will release the configuration used by the
DSP-100 in socket 1 using a configuration memory window at segment
CC00.
DSP-100 User’s Manual
2-11
2.2.2 Common Problems
Memory Range Exclusion:
The Enabler requires a region of high DOS memory when configuring a
DSP-100. This region is 1000H bytes (4KB) long and by default begins at
address D0000H (the default address may be changed using the "W"
option). If a memory manager such as EMM386, QEMM, or 386Max is
installed on the system, this region of DOS memory must be excluded
from the memory manager's control. Consult the documentation
provided with the memory manager software for instructions on how to
exclude this memory region.
Furthermore, some systems use the high memory area for BIOS
shadowing to improve overall system performance. In order for the
Enabler to operate, any BIOS shadowing must be disabled in the address
range specified for the configuration window. BIOS shadowing can
usually be disabled through the system's CMOS setup utility.
Socket Numbers:
The Enabler requires the DSP-100's socket number to be specified on the
command line and the DSP-100 must be inserted into the socket before the
Enabler is invoked. Some vendors number their sockets from 1 to N
while other vendors number their sockets from 0 to N-1. For the DSP-100
Enabler, the lowest socket number in the system is designated socket 0.
Card and Socket Services Software:
In order to use the DSP-100 Enabler for DOS, the system MUST NOT be
configured with Card and Socket Services software. If a Card and Socket
Services software is installed, the DSP-100 Enabler may interfere with its
operation and with the device(s) it controls. For systems configured with
Card and Socket Services, the DSP-100 Client Driver is the recommended
method of configuration.

3. Windows 95 Installation
To allow easy configuration of the DSP-100, an Windows 95 "INF"
configuration file has been written for the hardware. This configuration
file supports the DSP-100 in both addressing modes: block mode and
“com” mode.
3.1 Installing a DSP-100 Under Windows 95.
1. Insert the DSP-100 into any available PC Card socket.
2. The first time a new PC Card type is installed the New
Hardware Found window opens. After this first installation
Windows 95 will automatically detect and configure the card.
If the New Hardware Found window does not open, then skip
to the next section, “DSP-100 Resource Settings".
3. The New Hardware Found window provides several options to
configure the DSP-100 card. Click the "Driver from Disk"
option button. Click "OK" to continue.
4. An "Install from Disk" dialog box should appear. Insert the
diskette with the "DSP-100.INF" file, select the correct drive
letter and path, and click "OK". Windows 95 will browse the
path for the aforementioned files.
5. During the installation process, it may be required to supply the
computer with the Windows 95 CD or installation diskettes.
The DSP-100's serial devices will require the file
"SERIALUI.DLL". Insert the CD or diskette and click "OK".
IMPORTANT NOTE:
If the user already has these files installed on the
computer, or if the installation disks are unavailable, it
may not be necessary to supply the computer with the
Windows 95 CD or installation diskettes. If prompted for
the disks, click “OK”. A dialog box with an option to skip
will appear. Click the “Skip” button and the files will not
be installed. If these files exist in the windows system
directory, those files will be used.
The DSP-100 PC Card should now be configured. In the future, Windows
95 will automatically recognize and configure the DSP-100.

3.2 DSP-100 Resource Settings in Windows 95
Windows 95 maintains a registry of all known hardware installed within
the computer. Inside this hardware registry Windows 95 keeps track of
all the computer's resources, such as base I/O addresses, IRQ levels, and
DMA channels. In the case of a PC Card (PCMCIA) type board,
Windows 95 configures the new hardware using free resources it finds
within the hardware registry, and updates the registry automatically.
To view and / or edit hardware devices in Windows 95 use the system
Device Manager. To access Device Manager double click the System icon
in the Windows 95 control panel, or click the My Computer icon on the
Win95 desktop with the right mouse button and select Properties from
the pull down menu. Consult Windows 95 on-line help for details on the
use of the Device Manager.
Windows 95 handles the DSP-100 as a "parent/child device".
v The DSP-100 is the "parent device" and is listed under the
hardware class Multi-function Adapters in the device manager.
v Each serial port is a "child device" of the "parent device" DSP-100.
There are 2 child COM ports for the DSP-100 which are listed
under the hardware class Ports (Com & LPT).
3.2.1 Viewing Resource Settings with Device Manager
1. Start the Windows 95 Device Manager.
2. Double click on the hardware class Multi-function Adapters to
list hardware devices in the class.
3. The DSP-100 “parent device” belongs to this hardware class.
The device name for the DSP-100 is Omega Inc-PCMCIA Dual
RS-232 Serial Port Card.
4. Open the Properties dialog for the DSP-100 device, then click
the Resources tab to view the Input/Output Range and
Interrupt Request resource allocations. Examine and remember
the Input/Output Range, then close the properties window.
5. Double click the hardware class Ports (Com and LPT). Two of
the Logical COM Ports (COM2, COM4, etc.) listed in this class
are the “child devices” of the DSP-100 “parent device”.
3-2
6. View the Properties dialog for each COM port and examine the
Resources allocated to each port. Inside the Resource allocation
window two of the COM ports will identify the Omega
Inc-PCMCIA Dual RS-232 Serial Port Card as the parent
device. The Input/Output Range and Interrupt Request
resource allocations for these two COM ports will also match
the resource allocations of the DSP-100 “parent device”.
Figure 2. Windows 95 Device Manager
7. Use the COM Port device names (COM2, COM4, etc.) to access
any of the particular serial ports on the DSP-100. This name is
required by a Windows 95 application when accessing a
particular port.

is addressable in either mode from Windows 95.
1. Start the Windows 95 Device Manager.
2. Double click on the hardware class Multi-function Adapters to
list hardware devices in the class.
3. The DSP-100 “parent device” belongs to this hardware class.
The device name for the DSP-100 is Omega Inc-PCMCIA Dual
RS-232 Serial Port Card.
4. Open the Properties dialog for the DSP-100 device, then click
the Resources tab to view the Input/Output Range and
Interrupt Request resource allocations.
5. Several predefined Basic Configurations have been included
for the DSP-100. The table below defines the various
configurations. When the Use Automatic Settings check box is

6. Select a Basic Configurations that displays "No conflicts" in the
bottom display region titled Conflicting Device List from the
drop down list. Some applications may not be able to access
ports higher than COM4. To use the DSP-100 PCMCIA serial
ports with these applications you might be forced to remove
other serial communications devices from your system.
Figure 4. Windows 95 Resource Allocation
7. Windows 95 should have chosen an available Interrupt
Request setting automatically when the I/O address range was
configured by a Basic Configuration selection. This default
Interrupt Request setting should not need changed as long as
"No conflicts" is displayed in the bottom display region titled
Conflicting Device List. If you are satisfied with Windows 95
selection then skip the next step.
DSP-100 User's Manual

8. To modify the Interrupt Request setting click the resource
name and click the Change Setting button. An Edit Resource
window will open up. Inside this window click on the
up/down arrows to the right of the Interrupt Request value.
This scrolls you through all of the allowable resources for your
hardware. Pay attention to the conflict information at the
bottom of the window. Do not select a value that causes a
conflict with any other installed hardware.
9. If any changes have been made to the DSP-100’s configuration
the card will automatically be reconfigured to the new
resources specified. Any time a PCMCIA card of this type is
inserted Windows 95 will attempt to configure the card at these
resource settings. Click the Use Automatic Settings box to
reset this card type for automatic configuration.

4. OS/2 Installation
In order to use the DSP-100 Client Driver for OS/2, the system must be
configured as follows:
1. The system must be running OS/2 version 2.1 or later.
2. OS/2 PCMCIA Card and Socket Services support must be
installed. If PCMCIA support was not selected when OS/2 was
installed, it can be added using the Selective Install facility in
the System Setup folder. On OS/2 2.1 and 2.11, Socket Services
must be added separately. The necessary files can be found on
Compuserve in the OS2SUPPORT forum and may be available
elsewhere. These files are not available from Omega.
3. Omega's OS/2 serial port device driver, "QCOM" version 2.01
or later, must be installed. The DSP-100 will not operate with
the standard OS/2 serial port device drivers. Omega can not
guarantee the operation of the DSP-100 with any other third
party device drivers for OS/2.
4. There must be at least 16 bytes of available I/O space and 1
available IRQ.
After the system has been configured to the above specifications, the
DSP-100 Client Driver may be installed with the following procedure:
1. Copy the DSP100.SYS client driver file from the distribution
disk to any convenient directory on the hard disk.
2. Open the CONFIG.SYS file using any ASCII text editor.
3. Add the following line to the CONFIG.SYS file:
DEVICE = drive:\path\DSP100.SYS options
where options are the DSP-100 OS/2 Client Driver command
line options discussed in the following sections.
4. Save the CONFIG.SYS file, exit the text editor, shutdown the
system, and reboot to activate the changes.
DSP-100 User's Manual

4.1 Command Line Options
The DSP-100 Client Driver for OS/2 supports two methods of
configuration: using "system assigned" resources and using "user
assigned" resources. Both options provide full PCMCIA compliance and
functionality (including "Hot-swapping") but each has some advantages
and disadvantages as discussed in the following sections.
4.1.1 Configuring With "System Assigned" Resources
Allowing the OS/2 Plug-and-Play system to assign the hardware
resources to the DSP-100 is the ideal choice when only OS/2 programs
will access the serial ports. When configuring the hardware, the user
simply specifies a list of COM port numbers. When a DSP-100 is inserted
into a PCMCIA socket, the client driver will configure the card as a series
of COM ports, starting with the lowest available port number in the list.
Configuring a DSP-100 with system assigned resources can be a problem,
however, if DOS and/or Windows applications will be accessing the
serial ports. This is because most DOS applications write directly to the
communications hardware and the Windows' Control Panel also wants to
know the hardware configuration of the serial ports. In these cases, the
user may want to configure the DSP-100 with "user assigned" resources.
4.1.1.1 Example 1
DEVICE=C:\DSP-100\DSP100.SYS COM3
In example 1, the Client Driver will attempt to configure the DSP-100 as
COM3 and COM4. If COM3 or COM4 already exists in the system, the
DSP-100 will not be configured. Furthermore, only one DSP-100 can be
installed in this system.
4.1.1.2 Example 2
DEVICE=C:\DSP-100\DSP100.SYS COM7 COM3
In example 2, the Client Driver will attempt to configure the DSP-100 as
COM3 and COM4. If COM3 or COM4 already exists in the system, the
Client Driver will attempt to configure the DSP-100 as COM7 and COM8.
If COM7 or COM8 already exist in the system, the DSP-100 will not be
configured. Up to two DSP-100s can be installed in this system.
4-2
4.1.2 Configuring With "User Assigned" Resources
As mentioned in the previous section, allowing the OS/2 Plug-and-Play
system to assign the hardware resources to the DSP-100 is ideal for OS/2
programs but can be a problem if DOS and/or Windows applications will
be accessing the serial ports. This is because most DOS applications write
directly to the communications hardware and the Windows' Control
Panel also wants to know the hardware configuration of the serial ports.
For this reason, the DSP-100 Client Driver allows the user to request
specific hardware settings using a series of command line arguments of
the form
(port,address,irq)
port
specifies the beginning COM port number
address specifies the base I/O address of the DSP-100 in hexadecimal
and must reside on an even 16-byte (10H) boundary.
irq
specifies the interrupt level (IRQ) of the DSP-100 in decimal.
irq must be one of the following values: 3, 4, 5, 7, 9, 10, 11, 12,
14, or 15.
Each argument must be enclosed in parentheses and must be separated
from other arguments by a space on the command line. Within each
argument, the parameters must be separated using a comma (no spaces).
When a DSP-100 is inserted into a PCMCIA socket, the client driver will
configure the card as a series of COM ports, starting with the lowest
available port number in the list.
IMPORTANT:
If the user specified resources are in-use by other devices in
the system, the DSP-100 will not be configured.
4.1.2.1 Example 1
DEVICE=C:\DSP-100\DSP100.SYS (3,100,5)
In example 1, the Client Driver will attempt to configure the DSP-100 as
COM3 and COM4 using I/O addresses 100-10F hex and IRQ 5. If COM3
or COM4 already exists, or if the I/O address or IRQ resources are
already in use, the DSP-100 will not be configured. Furthermore, only
one DSP-100 can be installed in this system.
DSP-100 User's Manual
4-3
4.1.2.2 Example 2
DEVICE=C:\DSP-100\DSP100.SYS (7,120,15) (3,300,4)
In example 2, the Client Driver will attempt to configure the DSP-100 as
COM3 and COM4 using I/O address 300-30F hex and IRQ 4. If COM3 or
COM4 already exists, or if the I/O address or IRQ resources are already
in use, the Client Driver will attempt to configure the DSP-100 as COM7
and COM8 using I/O address 120-12F hex and IRQ 15. If COM7 or
COM8 already exists or if the I/O address or IRQ resources are already in
use, the DSP-100 will not be configured. Up to two DSP-100s can be
installed in this system.
4.1.3 Advanced Configuration Topics
For some applications, it may be desirable to specify the resources for one
DSP-100 while allowing the OS/2 Plug-and-Play system to assign the
hardware resources for any additional cards. This can be accomplished
by mixing the configuration methods on the DSP-100 Client Driver
command line
DEVICE=C:\DSP-100\DSP100.SYS (3,100,5) COM7
It is important to remember that when a DSP-100 is inserted into a
PCMCIA socket, the client driver will configure the card as a series of
COM ports, starting with the lowest available port number in the list.
Another common application requirement is to have a DSP-100 inserted
into socket 1 be configured as COM3 and COM4 while a DSP-100 inserted
into socket 2 be configured as COM7 and COM8. This type of
configuration is supported by appending a "=Sx" parameter after any
command line argument.
DEVICE=C:\DSP-100\DSP100.SYS COM3=S1 COM7=S2
DEVICE=C:\DSP-100\DSP100.SYS (3,100,4)=S1 (7,300,3)=S2
4-4
4.2 Monitoring The Status Of PCMCIA Cards
OS/2 Warp provides a utility called "Plug and Play for PCMCIA" that can
be used to monitor the status of each PCMCIA socket. In OS/2 2.1, this
utility is called "Configuration Manager". When a DSP-100 is inserted,
the Card Type for the appropriate socket will display "Multi-Function". If
the card is successfully configured, the Card Status will display "Ready".
If the card cannot be configured, the Card Status will be "Not Ready".
You can view the resources claimed by a configured card by
double-clicking on that card's line in the window.
4.3 Common Problems
Invalid I/O Address When Using OS/2 Version 2.1:
PCMCIA Card Services for OS/2 version 2.1 sometimes fails to supply a
valid I/O address when using "system assigned" resources. Use the
"Configuration Manager" program to examine the I/O address range
assigned to the DSP-100. If this range does not begin on an even 16 byte
(10H) boundary, the DSP-100 will have to be installed using "user
assigned" resources to force a valid configuration.
There have not been any reports of this problem with OS/2 Warp.
Resources Not Available:
When using "user assigned" resources, it is the user's responsibility to
ensure the I/O address and IRQ resources are available. For OS/2 Warp
users, the RMVIEW utility may be useful in finding resource conflicts.
Type "rmview /?" at an OS/2 command prompt for details. OS/2 version
4.00 comes with HARDWARE MANAGER, which is easier to use than
RMVIEW.
When using "system assigned" resources, if the user knows the port
number is available then the system may not have sufficient resources
available to configure the DSP-100. Again, the RMVIEW utility provided
with OS/2 Warp may be useful in determining the problem.
Regardless of the configuration method, each command line argument
specifies the first of two COM ports for the DSP-100. If any of these COM
ports are already installed, the Client Driver will not load.
DSP-100 User's Manual
4-5
Parameter Overlapping:
When installing the DSP-100, each command line argument specifies the
first of two COM ports. If these arguments overlap, the Client Driver will
not load. For example, it is illegal to specify DSP100.SYS COM3 COM4
because the first argument requests COM3 - COM4 and the second
argument specifies COM4 - COM5.
Insufficient Number Of Command Line Arguments:
The DSP-100 command line must contain at least one command line
argument for each DSP-100 to be installed.
4-6
5. Unix Support
The DSP-100 and other Omega asynchronous serial communications
interface products are supported in the Unix operating system by Omega
’s Unix Enhanced Serial Device Driver. This driver is not included with
the DSP-100, but may be purchased separately.
5.1 Unix Enhanced Serial Device Driver
The Enhanced Serial Device Driver provides a fully interrupt driven,
buffered input/output system for multiple RS-232 serial ports in an IBM
or compatible microcomputer using the SCO UNIX System V Operating
System. The Enhanced Serial Device Driver is a replacement for the
serial driver that is provided with the SCO UNIX operating system, and is
one hundred percent SCO UNIX compatible. It provides the same
functions as the SCO UNIX (Release 3.2) serial device driver plus the
following features:
v Support for Omega RS-232 Asynchronous Communication
Adapters, as well as, the system board serial port.
v A flexible configuration scheme which allows any I/O address or
interrupt request number that is supported by Omega's
Asynchronous Communication Adapters.
v Support for the National Semiconductor NS16550A device, an
enhanced version of the industry standard NS16450 device. The
NS16550A offers 16 character transmit and receive buffers that
greatly reduce interrupt overhead on the CPU.
v Support for up to 40 COM ports on multiple boards/IRQs.
v The Enhanced Serial Device Driver will support a total of 5 serial
adapters.
v Written in C for maximum efficiency.

6. Hardware Information
The DSP-100's two asynchronous serial ports are implemented using 2
standard 16C550 UARTs. Each of these UARTs requires 8 bytes of I/O
space. The DSP-100's serial ports are addressable in two modes:
1. 'Block Mode' : The two serial ports are configured in one
16-byte continuous block of I/O address space. The block must
begin on an even 16-byte (10H) boundary (e.g. 300H, 310H,
320H, etc.).

Figure 5. Block Mode Addressing.
2. 'COM Mode' : The two serial ports are configured at the
standard COM port I/O address locations. The ports may be
configured as COM1 and COM3; or as COM2 and COM4.
Each 16C550 UART contains 8 I/O registers. The last of these registers,
located at (Base address + 7), is referred to as the 'Scratchpad Register'
and provides no functionality to the UART. In place of this Scratchpad
Register, the DSP-100 implements an interrupt status register which can
be accessed at (Base address + 7) of any UART.

Figure 6. Interrupt Status Register.
When one or more UARTs have interrupts pending, the associated bit(s)
in the interrupt status register are set to logic 1. When all the pending
interrupts have been serviced for a specific UART, its interrupt status bit
will be cleared to logic 0 automatically. When all the pending interrupts
from all UARTs have been serviced, the entire interrupt status register
will return logic 0. The application program should not exit its interrupt
service routine until all pending interrupts from all channels have been
serviced (interrupt status register = 0) or no additional interrupts will be
received.
If an application requires the UARTs' Scratchpad Registers, the interrupt
status register can be disabled. Disabling the interrupt status register is
supported by the DSP-200 configuration software, which is operating
