To add a PostScript serial printer to port 2, become the superuser, and enter
the following:
# mkPS PostScript ttyd2
# /usr/lib/lpadmin -dPostScript
Refer to the IRIX Advanced Site and Server Administration Guide for more
information about configuring your printer.
You can connect an optional ASCII terminal to your server by using a simple
null modem cable with a 9-pin connector. See Table 4-4 for the serial port to
null modem cable pin assignments. Connect one end of the cable to the
terminal and the other end to the 9-pin system console port labeled tty_1 on
the main I/O panel. If you are building a 9-to 25-pin cable connection, the
pins will typically map as shown in Table 4-5

The ASCII terminal must be set with the following operational
characteristics:
• 9600 baud
• 8 bits
• 1 stop bit
• No parity
For your ASCII terminal to operate properly as the system console, it must
be plugged into the RS-232-compatible connector labeled tty_1 on the
system I/O panel.
