Is a USR 56k internal even going to work with Linux??? My gut reaction would say it is not. In any case (and because you're new I'll try to make this a little more verbose).... ppp0 is simply the first ppp type interface, and ppp interfaces are usually assigned to modems, the same as eth0 is the interface for your first ethernet card or tr0 for the first token ring card. You should be able to use minicom to test and see if it works. You need to know first which serial port the modem is supposed to be attached to. This is often part of the problem. PNP modems generally do not have jumpers by which you can force them to assume port parameters (com1, com2, com3, com4 - which BTW corresponds to ttyS0 through ttyS3). You will often use /dev/modem to connect to your modem but you find that /dev/modem is merely a symlink to /dev/ttyS0 (or 1,2,or3). The port is actually going to be one of the ttyS's. On a PNP modem that port has to be configured by some piece of software. Sometimes a PNP bios can set this up but more often, and nearly always on winmodems which this USR may be, the windows driver is what configures and enables the modem. Without this driver code, which won't work with Linux, the modem is unuseable. I'd suggest using minicom to test all four serial port addresses to see if you can find any modem at all. Just type minicom at the prompt in a text terminal. If you've never ran minicom before you'll probably have to do so the first time as superuser (root) and the command is usually minicom -s in that case. You access the help menu by pressing control-A and then the Z key. This will bring up the menu. Hit 'o' to get to the configuration menu. Then you select 'serial port setup' and can use /dev/ttyS0, /dev/ttyS1, /dev/ttyS2, or /dev/ttyS3 to directly access each serial port in turn. Be sure to use bit rates (option E) slow enough to make sure you don't have a problem in that regard that might mask other problems - I'd suggest 9600 until you figure out whether the modem works at all - you can optimize for speed later. After you've set the communications port and bit rate you can select option M from that help menu to initize the modem. You should see something like ATZ and then OK. If you see nothing then minicom is probably not able to find a useable modem at all. If you see ATZ (or a similar command) but there is no OK response then minicom probably thinks it has found a modem but cannot successfully communicate with it. I'm guessing you won't get a response at all if you're running an internal USR modem. You'll probably have to get an external modem or very carefully select from the limited set of internal models that will work with Linux. Hope this helps. -- Mike Rambo [EMAIL PROTECTED]
