[opensuse] Finding a modem
Hi all, I'm having very basic trouble with a modem card. It's an old one, and it's possible it's dead, misconfigured, or otherwise not functioning. However, my problem is more basic than that, even. I can see from hwinfo that the thing was probed successfully, and it has created /dev/ttyS0 and /dev/ttyS1, but I don't know which is the modem, and which the serial port, and I am having difficulty finding out. I tried using minicom to connect to the thing and sending it "AT" and "ATZ" commands (memory vaguely suggested that one of these was supposed to get a reply from the modem) but I couldn't get a response out of either /dev/ttyS0 or S1. Any suggestions on how to identify it, or determine if the card is in fact misconfigured in some critical way (or dead)? Cheers, Simon "You can tell whether a man is clever by his answers.

Sounds like what you are doing is right... Been awhile since I played with modems. This may be a dumb suggestion - likely is - but have you checked the permissions on the tty device files to make sure you have the proper access?

Hmm, I don't think that's my problem; it (minicom) doesn't complain of access rights, and I ran it as root as is necessary for the configuration phase. Thanks, Simon -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Just try varying the baudrates, all the way from 300 and up. Never mind bits and parity. (the default is almost always 8bit and no parity anyway). /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Uh, I should also have asked - is it an ISA or a PCI card? For the former, you may well need jumpering, special config utility or isapnp. -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It is a PCI, albeit an old one. I've dug out another from my scrap heap and am currently trying that.... fingers crossed! "You can tell whether a man is clever by his answers.

Well, that doesn't seem to be working either. So, I conclude it's not the hardware, but is in fact a software/config problem (most likely) Looking closer, I notice that the motherboard seems to have serial hardware of its own. Presumably that would account for ttyS0 and ttyS1, making this modem card ttyS2 or S3? If I look at the devices in the /dev/directory, I find that there are 8 /dev/ttyS* devices listed. If I run: stty -a < /dev/ttyS? on each of them in turn, the ones at S0 and S1 report full info, the ones at S2 and S3 report Input/Output error, and the ones at S4 upwards report No such device or address. Hmm, can't help thinking this is telling me something? Any thoughts? Thanks, Simon "You can tell whether a man is clever by his answers.

OK, I disabled the onboard serial using the BIOS setup. Now none of the serial ports report settings from stty. Now /dev/ttyS[0123] _all_ report Input/Output error, so that's clearly not a report indicating that a half-cocked device has been found. I guess that's a step forward. Meanwhile, hwinfo reports a product: '56K WinModem' or 'LT WinModem 56K Data + FAX' -- Is that one of those dreadful things that isn't really a device, and has to have proprietary drivers to work? Do I need to install a kernel module to drive it? Or should it go in the trash? Thanks again, Simon "You can tell whether a man is clever by his answers.

I'm reading late the thread, but what I was going to suggest: " hwinfo - --modem" finds and report on the modem. In your case, it would have reported the port if it existed. And yes, you need drivers. I have no idea which, sorry: if I find one of those modems it goes out the way it went in. I don't want any softmodem near me. Well, as you have real serial ports in your machine, I would try getting an external modem via serial port. They work (almost) always. - -- Cheers, Carlos E.

Bleargh, I think you're right. I loaded the "softmodem" stuff that I found in the distro, and it says that it doesn't support FAX functionality, so I guess--since that's all I wanted to do with this thing anyway--I'll have to give up until I can find a nice cheap external FAX modem Look out Craigslist, here I come :) (Anyone in the Denver area want to get rid of an external faxmodem?)

You can buy a driver module for certain fax/modems from the originators of the softmodem driver, last time I looked the pay for one had fax capabilities.
