Unexpected hangup by modem!!

This is weird!

The modem (Compac Presario 336-VSC internal), hangs up unexpected in the middle of an initilization (negotiation between, 2 modem when dialing my ISP). Or rather at the end of the init before it sends login/password (so that's not the problem!). This is the case when I dial my ISP using a PPP connection.
When I then try to connect via Hyperterminal under w95, the same happens, but earlier in the init (half way through).
The phoneline seems to work ok.
I'm mystified.

Any surgestions?

do you have call waiting on the line?  The modem is hearing noise or another signal and is hanging up.  Make sure there is only one analog signal on the phone line and that should be the modem.  if this doesn't work, you probably should install an entirely new phone line directly from the computer to the box.  If this doesn't work you have a faulty modem

Nope that's not the problem. And there are no other devices on the phoneline, such as a fax or the like.
My own guess is a bad modem.

Just to be certain: have you talked with your ISP to find out if it's a problem on their end? I recently had trouble connecting to my ISP (same sort of thing would happen), and it turned out that their server was down for DAYS! Try calling their tech support, if you haven't already.

Sorry, yes. That's not the problem either. My Inet connection is through where I work, and many other ppl use it daily. No problem there.

Guess I'm up for installing w95 again.

Try This:
Boot the Machine to a PURE DOS Prompt.
(NOT a Windows Virtual DOS Session)
at the Command Prompt type:
     Echo ata >com#
(where #=the com port of the modem ie Com1)
You should hear the modem going thru a set of test tones.
Now type:
echo ath >com# (again #=1 or 2 or 3 or 4)
the modem will hang up.
Now reset the modem S-registers to the default by typing
echo atz >com# (again #=1 or 2 or 3 or 4)
if this went correctly the modem is properly connected and in "virgin" state.
NOTE:   If you received the message
                Write Fault Error Writing device COM#
you have a hardware problem and I suggest you return the modem if it is still under warranty.
If you did not get the above message proceed as follows
Now reboot the machine to start-up Win95
open Control Panel - System Icon -Device Manager
Make sure you are viewing devices by type
Got to Modems icon on the device tree expand it and select your modem
when it is highlighted choose properties
first select the Connection tab
Make sure your data bits, parity & stop bits are set correctly
Make sure the Call Preferences section has the Cancel Call if not connected box set to a reasonable time (60 secs or so)
now click the Advanced button and make sure that if the
Use error control is selected
the required to connect is NOT
make sure HARDWARE flow control is being used.
and your modulation is set to standard.
and just in case this does not solve your problem select the
Record a log file box so that troubleshooting will be more effective..

Thanks for the effort. I have solved the problem by running a emergency recover cd. Guess the problem was in w95.
