Appreciate a lead of locating some code to dial phone numbers using
VoIP rather than my modem. Have switched my service from Verizon to
Comcast VoIP and now the utility I wrote to dial my personal phone
book using MSCommLib and AxMSCommLib procedures (Term code) of course
no longer works. Found nothing with my Google search but not exactly
sure of necessary key words. I am getting to old to enter 10 digits
without error<g>

would would it no longer work? Comcast VoIP just uses standard phone lines
to get back to the residential gateway device... it should work exactly like
a normal phone does
 
Neither the small dialer program I wrote or a shareware Fax program
(MightyFax) can access the modem. My program fails on the line
AxMsComm3..portopen = true and reports Err=8012 for which I have not
found an explaination.

Is the modem connected through a standard phone line to your VoIP gateway?
If so there should be no difference at all... unless you had a computer
based VoIP (software solution going through the computer only) which would
be the only reason this would not work, but if its just a standard phone
connection to a VoIP gateway, then sould work just like it did on a standard
copper land line
 
Smokey,

My telephones, along with my modem, connect directly to the Comcast
VoIP box (actaully they go out to the NIB and simply return to the
VoIP box where that line was severed from the Verizon phone line. So
my modem is talking to the VoIP box which in turn sends its
information out through the cable and somewhere down the road at a
Comcast site it "miraculously" feeds into the telephone system so I
can talk to the rest of the world. How is that for a non-technical
description.

If I work my way to the Properties tab for the Modem it tests out
fine - I think, here is the log:

Hi,

Error 8012 is "Application-defined or object-defined error." This error
(generally) comes from the driver for the device, and is relayed up by
MSComm32.ocx. What is the physical device? Is is a USB adapter? Can you
open it successfully using HyperTerminal?

BTW, if you are using VS 2003, you might prefer to download
DesktopSerialIO.dll from my homepage. This is simpler to use than MSComm,
though its use won't solve this particular problem, perhaps. For VS 2005,
you can use the built-in System.IO.Ports namespace.
