6.5 TESS Emulation
TESS (Teklogix Screen Subsystem) is the normal operating mode of Psion Teklogix
computers. Teklogix protocol emulation software resident on network controllers or
a Psion Teklogix Software Development Kit (SDK) and installed in the host
converts host screens to TESS commands. The 9150 Access Point is also equipped
with protocol emulation software.
Note: If the message “RESET: Press Enter” flashes at the bottom of the TESS
screen when you turn on the 7530, press the <ENTER> key once.
6.5.1 Configuration
Note: Each TESS session must have a unique name assigned to it. The title
you assign will be displayed in the Display Menu.
The process of renaming an existing TESS session and adding a new session is
described in the section titled, “Applications” on page 194.
A unique number must be assigned in the “Terminal #” parameter for each TESS
session. Refer to “Terminal #” in the section titled “TESS Settings” on page 212
for details.

the letter e.
