TESS Emulation
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 7535, 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 160.
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 176 for details.
6.5.2 Working With Multiple Sessions
To display another session in TESS:
• Go to the startup ‘Display Menu’. If you are in a TESS session, press
<CTRL><ALT><0> to go to the ‘Display Menu’.
• Type the letter corresponding to the application you want to launch.
For example, suppose the sessions are listed in the “Display Menu” as
‘ D TESS1 ’ and ‘ E TESS2 ’. To launch the session named TESS2 , type the letter e.
6.5.3 The Field Types
Fixed Field – displays information that cannot be changed from the keyboard.
Entry Field – allows the operator to enter data. This type of field is usually shown as: “........”
Match Field – the host computer loads data in the format of the expected entry. If the entered data does not match the expected format, the unit emits a long beep.
