If the test sentence appears on the terminal screen, but you do not see a "login:"
prompt when you press the terminal's Enter key, verify that there is a getty process
running on the serial port.
ps -def | grep getty
You should see output similar to this:
root 844 1 0 23:16:27 ttyd3 0:00 /sbin/getty -N ttyd3 dx_38400
root 843 1 0 23:16:27 ttyd1
This indicates that a getty process is running on both the system console (port 1) and
on port 3. If you do not see a getty process running on the desired serial port, verify
the serial port settings in /etc/inittab and rerun telinit.

Connecting a Modem

To attach a modem to your server, connect it to ports 2, 3, or 4 using a serial modem cable.
The serial cable must be appropriate for data communications equipment (DCE): The
data transmit and data receive pins are opposite those in a DTE cable. Also, the cable
must provide full flow control. See Appendix B, "Cable Descriptions" for information
about this type of cable.
See the /etc/uucp/fix-hayes or /etc/uucp/fix-telebit files for information on specific modems
supported (see step 5, below).
The following general procedures are used when connecting a modem:
1. Make sure that the power switch on the modem is turned off.
2. Attach the serial cable to the modem.
3. Attach the connector on the other end of the cable to the desired serial connector on
the server's I/O panel (port 2 in a single-module system, or ports 2, 3, or 4 in a
dual-module system).
4. Attach the modem power cord and turn on the modem.
5. Install the UUCP subsystem (eoe.sw.uucp), if it is not already installed.
The UUCP subsystem is shipped with the IRIX operating system, but is not
Note:
installed by default. Confirm that the UUCP subsystem is installed by using the
versions(1M) command. If it is not installed, see IRIX Admin: Software Installation and
Licensing for instructions.
