It appears that you have only one modem (SiS modem: Bus#=0, Device#=1,
Func#6). If you're trying to get this modem to work under Linux, you'd
better make sure this is a linmodem. This modem device is a part of the core
chip set (SiS PCI-to-ISA bridge or a.k.a. south-bridge). It could be AMR or
CNR type of modem.

You may visit SiS web site ( or PCChips web site to get more
information about the modem. OK, go to PCCHIPS web site first and find the
model you have. Then, find out which SiS chip set you have on the
motherboard. Then go to SiS web site to look for that chip set. Or just call

Hello all.

I've tried just about everything and I just can't get
this guy to work. Here's what I've done so far:

Distro = SuSE 7.1
mboard = PCCHIPS 810 LMR

Compiled a "vanilla" 2.4 kernel
Downloaded the PCTEL2.4 driver package
Did a make, make_install on both the pctel and
ptserial modules with no errors
insmod pctel, insmod ptserial. A lsmod shows both
modules loaded but tail -30 on /var/log/messages shows
the ptserial module but nothing from the pctel module.
Neither minicom nor wvdial can find the modem. Here's
a dump of lspci:

I've checked at the PCI site and in the Windows driver
and this is definitely a PCTel modem. I also looked
into the code for the drivers and 7013 is listed in
the code. Any help would be greatly appreciated.
