Configuring a Device for a Printer

Use this procedure to configure a RealPort device for a printer. See your operating system documentation for more information on configuring a serial device for a printer.

Procedure

1. In HP-UX, TTY devices require Data Carrier Detect to be high. This must either be tied high within the cable, or it can be forced high in the driver by entering this ditty command for the port in a startup file:

   ditty forcedcd ttya12

   The device, ttya01, is used as an example in this command.

2. Connect a proper cable between the port and printer. See the Digi One RealPort or PortServer Cable Guide.
3. Set the port to dev=rp on the Digi One or PortServer by entering this command at the root prompt:

   set port dev=rp ra=12

   This example sets PortServer port 12 to be a RealPort device.

   Note: If your Digi One RealPort or PortServer firmware does not support the dev=rp option, use dev=prn instead.

4. If you are using 8-pin RJ-45 cabling from the Digi One RealPort or PortServer to the terminal, set the port to altpin=on by entering this command at the root prompt:

   set port altpin=on ra=12

   This example sets altpin=on for port 12 of a Digi One RealPort or PortServer.
