Queuing Mode
6.5.12 Queuing Mode
In some applications, queuing mode can decrease the computer lock time. In queuing mode, the host computer may send several pages to a 7535 without waiting for a response. These pages are stored in a queue within the 7535 hand-held. The operator completes the entries on the first page and then, presses a function key.
The 7535 simultaneously transmits to the host and displays the next page in the queue. The computer does not lock, allowing the operator to enter data on the next page immediately. This continues as long as there are pages in the queue.
Queuing mode is used for repetitive tasks, and the queued screens look identical.
The 7535 displays a “Next” message indicating that a new page is on the display.
“Next” messages also contain information about radio communications: “NEXT-B” indicates that the 7535 has data to transmit to the base station. “NEXT-H” indicates that the base station has acknowledged a transmission. Unlike lock messages, “Next” messages do not lock the keyboard. Keying is allowed while
“Next” messages are displayed.
While queuing mode may improve apparent response time, it can present difficulties to hosts that are operating in real time. It should only be used after careful consideration of the host environment. The 7535 must be configured for queuing mode (see the “Queuing” parameter on page 183). Additional information on queuing can be found in the TESS (Teklogix Screen Subsystem) Manual.
6.6 ANSI Emulation
The Psion Teklogix 7535 in ANSI mode operates like most other ANSI terminals.
This means software that supports ANSI terminals requires little or no changes.
6.6.1 Configuration
To configure the 7535 for ANSI mode, the “Name” and “Type” of session – in this case, ANSI – must be specified in the Applications menu. This menu is described in the section titled, “Applications” on page 160.
Next, a unique number must be assigned using the “Terminal #” parameter. This number should be unique across the entire system – that is, each 7535 and each application session in each 7535 across your system must have a unique number assigned. This parameter is described in the section titled “ANSI Settings” on page 161.
Once the 7535 is configured, an ANSI operation can be selected from the startup
“Display Menu”.
