I have a US Robotics 56K PCI Fax modem in a Windows 7 PC.
Windows recognized it and installed a driver.
Device Manager says it is working properly.
With Hyperterminal, I can dialog with it and dial out.
I can use Windows FAX and Scan to send a fax.
So what's the problem?
I have a VB5 app with MsComm (mscom32.ocx) which does not work.
The key command is : MSComm1.Output = DialString$
In development mode, if I put a stop before this command, and proceed step by step, it works.
Thinking it was a timing problem, I tried DoEvents and a Timer delay, to no avail.
