6.6.12 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 7535/7530 without waiting for
a response. These pages are stored in a queue within the hand-held. The operator
completes the entries on the first page and then, presses a function key.
The 7535/7530 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 7535/7530 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 7535/7530 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 7535/7530 must be configured for
queuing mode (see the “Queuing” parameter on page 292). Additional information
on queuing can be found in the TESS (Teklogix Screen Subsystem) Manual.
6.7 ANSI Emulation
The Psion Teklogix 7535/7530 in ANSI mode operates like most other ANSI
terminals. This means software that supports ANSI terminals requires little or no
changes.
6.7.1 Configuration
To configure the 7535/7530 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 267.
Next, a unique number must be assigned using the “Terminal #” parameter. This
number should be unique across the entire system – that is, each 7535/7530 and each
application session in each 7535/7530 across your system must have a unique
number assigned. This parameter is described in the section titled “ANSI Settings”
on page 268.
