Serial Port
TESS print commands control the transfer of data to and from the serial and printer
ports on the 7535/7530. At the 7535/7530 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.
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.
