I've got Zoom V90 2985 USB modem. I read somewhere it should work with
Linux. I have Mandrake 7.2, kernel 2.2.17 that I recompiled to have the USB
support. (in config for USB questions answered YES). Everything was OK. I
launched command that I read in some kind USB Howto: mknod /dev/usb/ttyACM0
c 166 0. Made link from /dev/usb/ttyACM0  to /dev/modem and with minicom I
can ring anybody I want. The modem works fine. But... with kppp it's not so
easy. It doesn't want any additional ppp stuff because I already installed
them. When I set my connection up and make him connect the modem forgets to
dial the number... well it starts to give its noises as if it has dialed and
connected. When I try to connect one more time the kppp gives command
ATZATM0L1 and waits for OK that modem doesn't want to say. It looks like
kppp isn't patient enough because as far as I know it should first say ATZ,
then ATM0L1 or something. So nothing happens. I tried to switch different
things in kppp setup but didn't help at all. I changed once this end of line
from CR/LF to LF and instead of ATZATM0L1  it wrote ATZ which should be fine
but no OK was given by modem.
I read somewhere but it's good to patch kernel 2.2.17 with 2.2.18 pre-patch
but I don't know if my problem has anything to do with kernel. (BTW I don't
know how to patch kernel... although I know how to compile it... ;))

Please help me because modem is the only thing that keeps me using ms wind.
:)
Thanks in advance.
