We are an isp operating with the v.90 protocol.  We have customers with Rockwell HCF 56K PCI modems.  These modems are usually found in Compaq pc's. Some of them have no connection problems, but most cannot connect at all.  I have tried the init strings on the www.56k.com website and
have had some sucess, but not with all customers...Help

Can they connect to *ANY* other modem?
Within "Control Panels", is their modem correctly defined?
When you write "cannot connect at all", please elaborate.
Do they hear the telephone-line "dial-tone",
just before the modem starts to dial?
Do they hear the touch-tones being "dialed"?
Do they hear the two modems "squawking",
as they negotiate a connection?
Do they see a 'CONNECT wwwww/xxx/yyy/zzz' message?
What's the exact text of that message?

Have you tried the "troubleshooting" link at that URL?

I use to work with Rockwells alot.  We use to find that they would reach the host, connect, but then not transfer any data, then they would just drop off and give an error.  We found that by ucing some generic initialization strings, it would help.  Try using AT&F or AT^M as the init string within the program.  Rockwell knows they have problems hooking up to older mainframes as well as some standard dial up services.  Chech their web site at www.rockwell.com.

It sounds stupid but when all else has been tried and failed it sometimes works (and I hate it when it works because it is so stupid) but have them put 3 commas after the phone number and then try it.

I also work for a local ISP.  What we found to work is adding S32=98 in the Extra Settings found in the properties of their connection under the Configuration button.  This disables the V.90 protocol (instead uses V.32 or V.34).  They should be able to connect at about 28.8.  Ideally, try to locate the individual init string for that specific modem first.

But, PSYC01, why purchase a 56K modem, if you deliberately restrict it to 28800?  Am I missing something?

In the area I live in some of the phone lines are so bad that even a 14.4 connection is difficult to maintain.  I do agree Otta, the S32=98 is a last resort.  Sorry to advise so quickly.
