Using MSCOMM32.OCX can't get USR 56K w/Dell pc's to respond

We are upgrading a comm. module from VB3 with MSCOMM.vbx to VB6 with MSCOMM32.OCX v6.00.8169 DTD 6/24/98.  With the new control found pattern that Dell pc's with internal USR 56k modems from Dell will not respond most of the time (i.e USR Model 0484 & 0584).  

If switch back to old 16-bit comm module same modem works fine.  Happens on all operating systems.  On same Dell pc external USR works fine.  Also tested switching to internal USR Winmodem as well as a USR 56k PCI modem off the shelf (not from Dell) and worked fine on same pc.

In the old VB3 version of the software had same problem and was solved by upgrading to newer version of MSCOMM.vbx (v2.1.0.1 DTD 5/12/93).  In this case cannot find newer version of MSCOMM32.OCX.

Dell tech support heard of this problem and said try USR for a different driver.  Since the Dell with internal modem is so common I'm looking for a way to make the app work without having to ask everyone to change drivers and/or modems.  Thanks!

Here is your Solution. Tell your Client to Stop Using internal modem and go with External modem. By the way who is your programmer, he must be a genious. I have tried this before but Can't convert to vb6. Give him more money and tell to use the IP Control. I'm sure he'll be happy to that for you.

P.S. How come no one has answer this question before. You must give me 300 points now.

Hey, we're not in the business of giving out modems.  When a client has a new pc with a new modem we can't tell every one to just buy another one as well.  My programmer is good but this dude wants to argue about everything. Too bad arguing isn't an Olympic event.  I'll give him some points and see if it helps at all.
