Send Mile
This parameter controls the sending of a milestone from the 7535 after a “hey_you” command. Consult the Teklogix Screen Subsystem (TESS) User Manual for more information on milestones.
Next X
This parameter enables and disables the next messages used in queuing mode.
Kbd Locked
This parameter allows you to lock (set to “Y”) or unlock (set to “N”) the keyboard for all alphanumeric input in TESS. When the keyboard is locked, the function keys, arrow keys and the <ENTER> key are still functional. The 7535 emits an error beep if a character is rejected because the keyboard is locked. Changes to this parameter take effect only after the unit is reset.

Serial Port
TESS print commands control the transfer of data to and from the serial and printer ports on the 7535. At the 7535 computer, the value assigned at the ‘Serial Port’ parameter ranks which port the TESS print command will identify and use as the first to fourth port. The allowable options are: Any Available , 1st Serial ,
2nd Serial , 3rd Serial , 4th Serial and Disabled .

Features
Serial Out
This parameter enables serial port output fields.
Serial In
This parameter enables the serial port input fields. If enabled (set to “Y”), the TESS application has exclusive use of the serial port. Acceptance of data in a SI field is determined by the SI prefix and suffix.
SI mode
The possible values for this parameter are field (the default) and command . When the SI mode is set to field , data received through the serial port is displayed in the serial input fields. If you are using serial-input fields, make sure the “SI mode” parameter is set to field .
When “SI mode” is set to command , data received by the serial port is transmitted as
Passthrough data to the host.
Note: “Command” mode is supported by SDKs but not by emulations.
SI prefix
This parameter determines the start-of-message character on serial input. Enter an
ASCII numeric equivalent from 0 to 255 to represent the start character. A value of
0 (zero) indicates no prefix.
SI suffix
This parameter determines the end-of-message character on serial input. Enter an
ASCII numeric equivalent from 0 to 255 to represent the end character. A value of
0 (zero) indicates no suffix.
SI CRC
This parameter enables or disables CRC validity check on serial input. When enabled (set to “Y”), a packet is rejected if the CRC is not valid.
Also, when this parameter is enabled (set to “Y”), each time a DLE (^P=0x10) character is encountered in the serial input, it is removed and the character following it will be replaced with its 1’s complement.
