Linux uses a device file to communicate with a modem. Device files are located in /dev directory. A modem must use one of serial ports (/dev tyS0 - /dev tyS3). First determine which serial port to use for modem. You should use ttyS1 because ttyS0 is usually assigned to a back panel connector.
To configure serial port, use setserial command with information that you recorded above. Using example values above, you would type following into terminal window:
setserial /dev tyS1 uart 16550A port 0xdc00 irq 11
You can verify that modem is working by sending it command to dial. For example type following into terminal window:
echo "atdt5555555" > /dev tyS1
If you hear modem dial, close connection by typing:
echo "atz" > /dev tyS1
If you didn't hear modem dial, make sure you have modem speaker turned on by typing:
echo "atv" > /dev tyS1
Then try dialing again.
To have Linux automatically configure your modem at boot time, add setserial line that you used above to file /etc/rc.d/rc.local
Assuming that you are using GNOME window manager, click on "foot" icon on taskbar to open menu. Select "Programs" and open "File Manager". In File Manager, navigate to directory /etc/rc.d and right-click on file rc.local. Select "Open with..." in popup menu. In "gmc" dialog box, select "gnotepad+" and click on "OK" button. At bottom of file, type setserial command line and then save file.

Sometimes configuring a modem is not as easy in Linux as it is in Windows, but alternative is to continue to use Windows and beg for Bill Gates permission to upgrade your hardware (XP product activation). ---------------------------------------------------------- Resource Box: Copyright(C)2002 Bucaro TecHelp.
