Psion Teklogix 8525/8530 Vehicle-Mount Computer User Manual
6.7.7 Lock Messages
When information is transmitted to the host computer, the keyboard locks to
prevent further data entry until the 8525/8530 receives a reply. A locked state is
indicated by either “LOCK-B” (base) or “LOCK-H” (host) in the lower left
corner of the display.
When the reply is received by the 8525/8530, the lock message disappears and the
keyboard can be used again.
6.7.8 Control Commands
A group of [CTRL] key commands can be used within TESS to dictate how the
8525/8530 will operate under a variety of conditions.
• [CTRL] [P] – Reprints the last print page sent from the host. This key
combination will not print anything if a print page from the host was not
previously received at the 8525/8530 vehicle-mount.
• [CTRL] [S] – Displays the 8525/8530 status continuously. Below is a
sample status line as it might appear at the bottom of your screen:
Lock-B/Lock-H fld enh “application name”
• [CTRL][T] – Displays the 8525/8530 status with the terminal number
instead of the name.
Lock-B/Lock-H rep “terminal nn”
• [CTRL] [H] – Displays a menu of available hosts.
6.7.9 Resetting A TESS Session
Resetting a TESS session requires that [CTRL] C be pressed three times within a
two second period to generate the “RESET – User request” message.
• Press and hold down the [CTRL] key, and press the [C] key three times
within a two second period.
• Press [ENTER].
This procedure restarts the TESS session without affecting the rest of the
8525/8530.
