I having problems with modems. It started out with an Amquest 56K internal and
also happens with the USR 56K external. These problems occur in Windows98 and
L-M 6.1.
Problem 1; The modem goes off hook, there is the dial tone, the number is
dialed, the dial tone comes back. Sometimes the modem resets itself, most times
not. I have verified the modem settings that are software related and used a
terminal program to verify individually the settings of the modem profiles and
S registers, all are at factory defaults.
Problem 2; The dial up procedure goes fine, but the modem hangs up. This always
occurs when the two machines are settling on the ppp parameters. In particular
here is a snipit of my ppplog:

Repeated dialing attempts results in the following:

Of particular note you'll see on an unsuccessful attempt I recevie what I take
to be a termination request from my ISP's host resulting in a modem hangup.
What I don't understand is why this happens as nothing has changed when a logon
is successful.
I have talked with my ISP and they say it has to do with some irregularity in
the Rockwell chipset used on the Amquest and USR modems. Anyone aware of this
issue?
My last problem is with frame errors during a session. They are not escessive
but Netscape stalls a lot and throughput is noticably slow. I remember seeing a
docuemnet somewher on the net what causes this but I cannot not find it. Can
anyone point me to it?
TIA
