Question
modem problem
Hi
I have an Ibm thinkpad, and am trying to make my internal modem work. The proper driver for the modem is ltmodem-kv_2.4.18_18.8.0-8
My kernel was 2.4.18-14 and I upgraded to the latest kernel 2.4.18-18.8.0. I installed the rpm package for the modem, but "kppp" is returning the error "sorry, can't open modem".
I have had the modem working before under the above kernel, but I recently had to re-install redhat version 8. For the record, when I did the upgrade of the new kernel, I didn't do it via the "up2date" utility, but instead downloaded the rpm package and installed it. But after I did that, I only got the option of booting into the new kernel, unlike when I did it the first time via "up2date", the system kept my old kernel version.
Right now, I need to know how I can get this modem up and working again. any help will be appreciated.

Hi,
Verify that the /dev/modem link still exists.
(Some apps default to /dev/modem)
ls -l /dev/modem
It should be pointing to a ttySx device:
/dev/ttyS0 - com1
/dev/ttyS1 - com2
Sometimes:
/dev/ttyS00 - com1
Try using minicom to see if you can initialize the modem.
Internal modems are sometimes a bit trickier to get working, mainly because of the IRQ conflicts.
Enter cat /proc/interrupts
See which IRQ the modem is using (3 or 4).
Hmm.. I remeber a friend that had to disable COM2 in his CMOS to get an Internal Modem to work, otherwise they conflict. Although the Internal modems mask IRQ 4 with COM1/3 and IRQ 3 with COM 2/4, it doesn't mean you have 4 usable COM ports,because once the modem goes high, it takes over that port, anything else on it will freeze.
If you can access the modem via minicom, check the pppd options for which modem you are trying to use.
