Resolution / Answer
Setvar
To instruct the printer to turn TELNET on or off:
! U1 setvar "ip.telnet.enable" "value"
! U1 setvar "ip.telnet.enable" "value"
Value
"off" = disables telnet protocol
"on" = enables telnet protocol Default "on"
Getvar
To instruct the printer to respond with the TELNET status:
! U1 getvar "ip.telnet.enable"
! U1 getvar "ip.telnet.enable"
Example
This setvar example shows the value set to "on".
! U1 setvar "ip.telnet.enable" "on"
When the setvar value is set to "on", the getvar result is "on".
Note: The telnet menu and support for port 23 have been removed in the Link OS 6 firmware.
