This printer setting determines the behavior of the serial
port interface. It selects one of three serial communication states:
DTE, DCE or Autodetect.
Setvar
To instruct the printer
to change the serial port interface type:
! U1 setvar "comm.type" "value"
Values
"auto" =
Autodetect
"dte" =
Force DTE (Tx on pin 2)
"dce" =
Force DCE (Rx on pin 2)
Default
"auto"
Getvar
To instruct the printer to respond
with the current serial port interface type:
! U1 getvar "comm.type"
Examples
In this example, the
getvar
retrieves
the serial port communications state.
! U1 getvar "comm.type"
This
setvar
example
sets the communications port state to auto-detect.
