### 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.
