The UNIX command “stty” allows a user to view or set the options for a terminal port. This command can be used as a

tool to aid in troubleshooting modem configuration problems. A sample stty output might look like this:

zappa:/> stty -a

speed 19200 baud; line = 0; susp = ^Z; dsusp <undef>

rows = 0; columns = 0

intr = ^C; quit = ^\; erase = ^H; kill = ^U; swtch = ^@

eof = ^D; eol = ^@; min = 4; time = 0; stop = ^S; start = ^Q

The instructions to configure an HP-700 series workstation, running HP-UX 9.x, are detailed in the following list.

NOTE: Superuser privilege is required to perform these instructions!

1. Connect the modem into the serial port on the back of the CPU case. Verify that the AC power cable is

connected. Verify that the phone line goes into the modem. Verify that the serial communication cable

connects the modem to one of the HP’s serial ports. Verify that the modem is powered ON.

2. Login and run the SAM utility. To add a modem to the known devices, go to the Peripheral Devices-

>Terminals and Modems->Actions->Add Modem... screen. Press OK to a popup about no terminals or modems

found, if applicable. Press OK on the popup window about port availability. Configure the following:

Modem Configuration Parameter Recommended Value

(Defaults in BOLD)

Mux/Serial Card Choose one from the list given or take default.

Port Number Choose one from the list given or take default.

Speed (baud rate) 19200

Use Device for Calling Out NO

Receive In-coming Calls (start getty process)

YES

CCITT Modem (used for international calling)

Press OK to add the modem. Another popup should appear, stating that a new device file was created. Press

OK and exit SAM. Verify that a new getty process has been started for the modem by executing this command

(a sample output has also been provided):

ps -ef | grep getty

root 1359 28831 1 14:15:10 ttyp2 0:00 grep getty

root 245 1 0 May 7 console 0:00 /etc/getty -h console console

root 1068 1 0 14:12:44 ? 0:00 /etc/getty -h ttyd00 19200

NOTE: ttyd00 is the device file name given by SAM. 19200 is the stated baud rate.

3. Verify that the following line has been put into the /etc/inittab file. If not seen, put it there.

a0:4:respawn:

/etc/getty -h ttyd00 19200

where ttyd00 is the device file name given in SAM, and 19200 is the desired baud rate.

If the inittab file was modified, execute this command for the changes to take effect:

init q
