Problems with a Conceptronic PCMCIA c56cls modem
Hallo, I have recently intalled SuSe 9.1 in my laptop. The computer has an winmodem that it's not supported by Linux. So, I decided to buy a PCMCIA modem. In concret, I have the c56cls by Conceptronic. This modem is supported by Linux, but when I try to connect, SuSe gives me an error. It says that it cannot open the modem! It's very strange! When I start the system, cardmgr beeps twice and it seems that it configures the modem... The first thing that I thought was that maybe the modem wasn't supported by Linux but... If I run the machine with Knoppix Live cd, the modem works perfectly and I can connect without problems! To connect to the net, I use the dialer KPPP, and it is well configured. Does anybody have an idea that could explain the reason of the problem? Does anybody know how I should overcome the problem?

ok, that's good.

What does "ls -l /dev/modem" show after plugging in the card and the two beeps? if it shows a link pointing to /dev/cua?, then please eject the card and (as root) do a "rm /dev/cua*". Reinsert the card. "ls -l /dev/modem". Now it should point to /dev/ttyS? and it should actually work. -- Stefan Seyfried

Have a look at /dev/modem, I had a similar problem where it was a link to /dev/cua0, which was dead long past, I changed it to link to /dev/ttyS0 and it all worked. /etc/pcmcia/serial seems to be where it's set up to use cua and says we need to keep track of them if the device files exist. After rereading that file, I've now removed /dev/cua* and shall see what happens on the next reboot, hopefully I shall see it linked properly. Regards Sid. -- Sid Boyce ....

After reboot, it /dev/modem -> /dev/ttyS0 now. Regards Sid. -- Sid Boyce .... Hamradio G3VBV and keen Flyer =====LINUX ONLY USED HERE=====

I would not bet what will happen if you just pull out the card and reinsert it, maybe you would get back /dev/cua0.
Regards Sid.
anyway, the /dev/cua* are only present by accident and by just doing a brave "rm /dev/cua*" you are getting rid of the problem. There is no even a kernel part for the cua devices any longer ;-) Also, the pcmcia/serial script could be patched to no longer watch out for cua*, but since we like to add as little suse-patches as possible, just removing the cua* is the easiest fix. -- Stefan Seyfried
