I am running a 300 mhz k6-2 on an aopen MOBO (AX59 Pro) with 64 mB RAM, I have used a best data win-modem V.90) and a Hayes external V.90 Hard Modem (signature Series <----their top of the line), all to the same result! A Constant disconnection. Call waiting is disabled, and I have tried different wall sockets all over the house to no avail? is it my modems? or is something else I havn't caught?

Does your ISP run on equpment from 3Com? Namely the HIPer DSP T1 and T3 type.
If so, there is a still unresolved serious problem regarding disconnects versus v.90 Rockwell based modems during speed-shifts.
The emergency cure is to disable speed changes, which is done with the parameter %E0 - which disables line quality check.
Since this will prevent you from speedchanges DURING the connection, you should try to connect at highest speed possible initially.
Test that out.
Here's a sample string you can add and check out:

AT&F%E0+MS=12,0,45333,56000

This is for a voice capable modem.
If it connects without much struggle, try setting a higher
value for "lowest connect speed" (in the sample set to 45333)
Valid values would be for instance
53333 52000 50667 49333 48000 46667 45333
(ONE of them)

If this helps and the sound gets annoying: Try
AT&F%E0M0+MS=12,0,45333,56000

Nick -

Sorry but there could be a number of problems ranging from your serve being busy to your configuration:

1. Your modem may be plugged into a shared slot - try plugging it into a different (PCI) slot. Then re-installing the drivers.

2. Ensure it's the right version of drivers that you're installing.

3. Ensure that you are inputing the correct TCP/IP DSN server information.

Questions:
- What kind of errors are you getting - specifically?
- Does your modem dial?
- Is your modem detected?
- Why the new modem - hopefully you didn't have a storm anything lately??? :)
