Hey,

I've just installed Slackware 10.1. Two things surprised me. Neither my modem or sound card were detected, though both worked in Slack 9.1. I can work around the sound issue, until (or if) I find a solution, but internet access is essential. Anyway, I followed the steps provided here:

This at least got the system to see my modem (my thanks to the author). Using KPPP, I configured my modem on ttyS3, not ttyS4 as I had initially set it up during installation. When I queried the modem, the system recognized it and responded something like this:

(I copied that from the aforementioned article, but my output wasn't too different.)

I tried to dial out and was told that the modem was busy. I checked /dev/modem and saw that it was linked to /dev/ttyS4. I rm-ed /dev/modem and linked /dev/ttyS3 to a new /dev/modem. I'm still getting the "modem is busy" message, whether I try to query the modem or dial out.

My modem is a 3Com/US Robotics 5610. I'm running Slack 10.1 on a 900 Meg Celeron with 128 MB RAM.

Any assistance would be greatly appreciated

I usto have the 5610 and if my memory servers me correctly it wont work on anyother serial port except ttyS4. The port is hardwired into the board and can't be changed to anything else. So you are going to have to change everything back to ttyS4.

Thanks. From the lack of responses I got on this issue in relation to the number of views, I figured there might be no answer. On Slack 9.1, /dev/modem points to /dev/ttyS4. I guess I was so excited to get some interaction with the modem, I didn't really think about this logically.

Thanks again.
