Software Product Description
PRODUCT NAME:
RSTS/E-2780 (CTS-500-2780),
SPD 10.50.2
Version 3
DESCRIPTION:
The RSTS/E-2780 Emulator runs as a user job under
a suitably equipped RSTS/E or CTS-500 system, providing emulation of an IBM 2780 Remote Batch Terminal. It will support transmission and reception
from/to card reader and line printer, and/or mass
storage devices, such as disk and magnetic tape.
General characteristics of DIGITAL's PDP-11 based
2780 products are given in Section B.
OPTIONAL SOFTWARE SUPPORTED:
None
The RSTS/E-2780 transmits files stored on any medium supported by the host operating system. It stores
files on any output medium supported by RSTS/E except DECtape. Magnetic tape operation may cause
timeout errors, unless the tape is positioned at the
start of the file when transmission or reception is
about to begin. In addition, files can be printed on
any line printer supported by the host operating system except the LS-11, a 60 line-per-minute printer.
(Such printers can be used in off-line mode, however,
wherein they print files temporarily stored on disk or
tape.)
UPDATE POLICY:
Software Updates, if any, released by DIGITAL during
the one (1) year period following installation, will be
provided to the customer for a media charge. After
the first year, updates, if any, will be made available
according to then prevailing DIGITAL policies.
RSTS/E-2780 also supports a spooling feature,
wherein users running with the RSTS/E-2780 can
queue one or more files for subsequent transmission.
Due to the processing requirements of the 2780 protocol, RSTS/E (CTS-500) response time may incur
perceptible degradation during transmission or reception.
MINIMUM HARDWARE REQUIRED:
• Any valid RSTS/E (CTS-500) configuration with sufficient memory for the expected number of users,
plus 8K words of memory to accomodate the Emulator.
• DP11, DU11, or DUP11 Synchronous Line Interface
• KG11-A Communications Arithmetic Element
OPTIONAL HARDWARE SUPPORTED:
Any mass storage device except DECtape supported
by RSTSE (or CTS-500) can be used as a source or
target of transmission files.
PREREQUISITE SOFTWARE:

• RSTS/E Operating System, Version 6B
• CTS-500 Operating System, Version 3

-3SECTION B: 2780 Emulator GENERAL DESCRIPTION
2780 Emulator is the collective name for the set of
software products that allows various DIGITAL operating systems to emulate the operation of an IBM 2780
Model 1 or 2 Data Transmission Terminal with the
multiple record option. Emulation of the 2780 permits
communication between such DIGITAL systems and
(1) the following IBM Remote Job Entry programs
supporting the device: OS/HASP, OS/ ASP, DOSPOWER and OS/RJE, or (2) a second DIGITAL supplied 2780 Emulator.
The following DIGITAL operating systems support the
Emulator for the 2780 Model 2: RSTS/E (CTS-500),
RSX-11D, RSX-11M, RT-11 and DECsystem-101 . In
addition, a COS-310 based emulator is available
which emulates the Model 1 2780. Section A gives the
distinguishing features of the particular 2780 Emulator
described by this SPD. The remainder of this section
describes items common to all PDP-11 2780 emulators.
OPERATION:
After the system operator starts the 2780 Emulator, it
solicits and responds to console command input.
Transmission: All 2780 Emulators can transmit data
from card readers, if they are present in the system,
and transmit data files from disk storage devices. The
RSTS/E 2780 Emulator has the added capability of
spooling or queueing transmission requests from
timesharing users.
All 2780 Emulators transmit EBCDIC and binary data.
Since the host systems use the ASCII character set,
however, they accept ASCII characters for transmission and then perform automatic character conversion. No conversion is performed on binary data.
The physical units of data that are transmitted are
called blocks. Blocks are divided into logical units
called records. Maximum block size is 400 characters; maximum record size when transmitting to IBM
operating systems is 80 characters, and when. communicating with other 2780's or 2780 Emulators, the
record size is variable up to 132 characters. Records
that are less than maximum allowable are either extended to the maximum by blank filling, or transmitted as is, at the user's option. Up to seven (7) records
can be transmitted per block.

Reception: All 2780 Emulators can print received
character data on a line printer, if one is present in
the system. In most cases, the software simulates limited-function vertical format control (VFC) by providing Top of Form (Skip to Channel 1), Print-andSpace-1, -2, or -3 line(s) functions, and skip to channels 2 through 8, all of which cause modulo 8 line
space operation--i.e., skip to the next line which is an
even multiple of 8 from Top-of-Form. Both 64- and
96-character line printers are supported. However,
support of line printers which are too slow to keep up
with the speed of the communications link (i.e., LS11
and LV11) is limited to "off-line" or DIGIT AL-toDIGITAL usage, because their speed can cause timeout errors in an IBM system.
All Emulators write files onto disk storage devices. In
such cases, a separate file is created for each received file.
All 2780 Emulators receive EBCDIC or binary data.
They can automatically convert EBCDIC data to ASCII
upon reception, or EBCDIC data can be written to a
file by the use of the binary mode.
Maximum receive block size is four hundred (400)
characters. The maximum receive record size is a
two-character escape code, plus one hundred thirtytwo (132) data characters. Up to seven (7) records
can be received per block.
All Emulators provide automatic answer to dial-in
rings.
Modems and Data Links: All 2780 Emulators support
operation over synchronous data links, in Point-toPoint Contention mode only, at speeds up to 4800
baud. Bell 201 or 208 modems or equivalent are
specified. Operation with other modems is not precluded, but warranted support does not apply in
these cases.
Data link control characters are supplied automatically by the Emulators. On transmission errors, the Emulators will re-try up to seven (7) times· before declaring the link dead.
Configuring PDP-11 2780 Emulator Systems: Configuration requirements for each Emulator are defined in
Section A. Briefly, the PDP-11 2780 Emulators require
the following hardware beyond the standard operating
system configurations:
