When my ISP changed pop providers from one using a Cisco system to one
using a Livingston Portmaster 4 (Livingston was since purchased by Lucent)
I had irregular problems with my modem locking up tight in any OS (Win95,
Linux and FreeBSD). Even after the phone disconnected, pppd did not
realize that the connection was dropped and when I killed pppd, I could
not even get any response from the modem with minicom. The only recourse
was to reboot.
My old modem was a Zoom K56flex internal flashed to V.90. I got an
external Diamond SupraExpress 56K and that has worked flawlessly even with
the bad Portmaster. Apparently Lucent never could correct the problems
with the Portmaster, so they ended its life cycle and it has since been
replaced. I have not tried my old modem with the new system, but I never
had any trouble with it on any other system (CompuServe, Freeswwweb and
ppp to a Cisco router my office always worked fine).
