I have been having these weird modem problems that are driving me
nuts. A couple of people have suggested it is a hardware conflict, but
win95 doesn't report any. My machine is a 486dx266 with 8MB
RAM. Microsoft serial mouse on com1. Diamond Stealth 24 video
card. The machine is 2+ years old.


The symptoms:

1. Zoltrix 14.4 internal fax-modem (on com2, com2 on my io card is
disabled) worked great under win3.1. I install win95, and I can do
anything *once* (use a phone dialer, connect with ppp, use
hyperterminal), then I must reboot to get it to talk to me again
(win95 reports no response from modem). Also, it doesn't work with
Microsoft Fax (hangs on "initializing modem") or any other fax program
I have tried. Zoltrix says it has tested that exact modem and it works
fine with win95. They say it must be a hardware conflict.

2. Any time I use add new hardware to add com2 or my modem, the mouse
hangs when I finish installing and I have to reboot.

3. I tried a Multitech external 28.8 modem. Enabled my io card
external com2 and removed the internal modem. Win95 saw the com port,
but not the modem (it didn't detect any modem on com2 at all). A
friend tried it on his machine and win95 saw the modem. My external
com port has never been used, so it possibly could be faulty, but
win95 did see and install the port itself.

4. I tried a USR Sportster 288 vi internal modem. Disabled the com2 on
the io card. This one faxes and connects and disconnects
beautifully. Every time I try to use ppp, it fails with either "could
not negotiate a compatible set of network protocols" or "could not
connect to server". I can see in the log that a connection is being
established but the failure happens bringing ppp up. I can use
dial-up-networking with this modem to dial up to work and connect with
a single screen (the dun post-connect screen), but ppp always fails.

USR suggested a clean install of win95, which I did (I wanted to
repartition my hard-drive anyway). Now I have no autoexec.bat or
config.sys. Same problems. A friend tried the modem in his machine
with no problems. I have gone over my ppp config with my ISP screen by
screen, and ppp works with my Zoltrix anyway. Possibly there is some
combination of serial port and modem settings (speed/flow
control/error control) that I haven't tried, but I did try speeds down
to 19.2.

------

I bought a new io card with a 16550 UART since my current one doesn't
have one. I will try that with the external Multitech, but I haven't
had a chance to install it yet.


Any ideas? Any suggestions for how to figure out what this problem is?
I was thinking of disabling the mouse by unplugging it and removing it
from device manager and seeing what happens. Is this enough to disable
it?


Any help at all would be appreciated - please respond by email.

Thanks!!!
