I have the same card, and it's not a Winmodem.  However, it does seem
to have trouble when both the ethernet and serial are in use, and it
can be finnicky that way.

My advice is to do an ifdown eth0 (or ifconfig eth0 down) before
trying to use the tty.  It may also help to run a 2.4.0-pre10 kernel
so the serial stuff is handled automatically by the kernel's serial
driver instead of pcmcia-cs, which I don't have much faith in.

Also, I've noticed some bad interactions between pump (DHCP client)
and PPP, so you may want to disable DHCP in /etc/pcmcia/network.opts
(and run /etc/init.d/pcmcia reload) while using the modem.  pump seems
to hog the default route even when there's no DHCP server to be found,
and there doesn't seem to be an easy way around it.
