6.7.12 Queuing Mode
In some applications, queuing mode can decrease the computer lock time. In queuing
mode, the host computer may send several pages to an 8525/8530 without waiting for
a response. These pages are stored in a queue within the vehicle-mount. The
operator completes the entries on the first page and then, presses a function key.
The 8525/8530 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 8525/8530 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 unit 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 8525/8530 must be configured for
queuing mode (see the “Queuing” parameter on page 225). Additional information
on queuing can be found in the TESS (Teklogix Screen Subsystem) Manual.
6.8 ANSI Emulation
The Psion Teklogix 8525/8530 in ANSI mode operates like most other ANSI terminals.
This means software that supports ANSI terminals requires little or no changes.
6.8.1 Configuration
To configure the 8525/8530 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 200.
Next, a unique number must be assigned using the “Terminal #” parameter. This
number should be unique across the entire system – that is, each 8525/8530 and
each application session in each 8525/8530 across your system must have a unique
number assigned. This parameter is described in the section titled “ANSI Settings”
on page 201.
Once the 8525/8530 is configured, an ANSI operation can be selected from the
startup “Display Menu”.
