The following procedures have been tested with Red Hat Linux 6.1 and 6.2 but should work with all modern Linux distributions. In Linux, make certain that the BIOS COMport settings are on actual addresses and not automatic.
The following instructions assume you know what COMport the modem should be on (based on the BIOS settings) and that you have minicom installed. To determine if minicom is installed, go to a console screen and issue the command rpm -qa | more. If you scroll through the list and see no mention of minicom, then check your Linux installation instructions, or visit your distributor's Web site and do a keyword search for minicom.
Please note that Linux commands are case and space sensitive!
1. Log in as root in a console.
2. Enter the password at the password prompt.
3. At the console prompt, type minicom -s, or, if you want to see display in color, type minicom -s -c on.
4. You will get the [configuration] menu.
5. Arrow down to Serial Port setup and press Enter.
6. Look at line A and press A to edit the line: COM1 should read /dev/cua0 and COM2 should read /dev/cua1 (and note the S is upper case and everything else is lower case). [Note: To use the external modem to both call out and answer, change to dev/ttyS0 (, 1, 2, or 3).]
7. Press Esc after you make any necessary changes on line A -- this will bring you back to the [configuration] menu.
8. Arrow down to Save Setup as dfl and press Enter. You will get a Configuration Saved message -- this will bring you back to the [configuration] menu.
9. Arrow down to Exit and press Enter. If you have set up the modem correctly, it should now say initializing modem and bring up some AT commands. If the modem does not respond correctly, make certain the modem is plugged into the correct COMport and the address is setup correctly in the BIOS. If you would like to prove that the modem dials internally, you can try this after you get the AT commands: type ATX3DT123456 [enter]. If you hear the modem dialing without the telephone line, the modem setup is finished and you can continue to the next step.
10. To exit minicom and go back the console prompt, press CTRL A then X.
Note: If you use a Red Hat 6.1 or higher distribution, as soon as you boot into Linux the system will find a new serial modem. You have to follow the instructions on this screen to make certain Linux knows that there is a new modem in the system.
