Anyone have any source code concerning sending a fax with the MSComm control?  I am a generous person and will pump up the point value for help and offer points to anyone that can provide pointers.  I need to communicate with Class1/2 modems.  Please help.

FAX Class1 and Class2 command set specifications are copyrighted and you have to pay to get them. However, there is unofficial and not so detailed specification for Supra modems which might help you.

Download them at:
ftp://ftp.supra.com/pub/commarchives/gen_info/class_1.txt
ftp://ftp.supra.com/pub/commarchives/gen_info/class_2.txt

...or view html at:
http://www.hylafax.org/Modems/Supra/class1.html
http://www.hylafax.org/Modems/Supra/class2.html

I worked with voice (not standardized, CirrusLogic) and data modems but I did not deal with fax. However I examined class1 specification and it seems easily implementable. Pay attention that those .txt files tend to describe in detail what is happening during faxing session, but note all places where it says that "modem does" something, so this is additional information which must not scare you off.

Another thing you need is graphics format of data that shouls be transmitted or received during fax sessions. It is a pretty simple monochrome image format, here goes a link with draft specification of that T.4 fax image format:
http://www.dcs.ed.ac.uk/home/mxr/gfx/2d/CCITT-t4.txt

I hope that this helps a bit, but you need to experiment a lot with this.
For the start read fax class1 specification and try to test with fax commands in some terminal program, issuing commands directly to modem/COM port (try using HyperTerminal), to see response from modem.

It would be good if you at least have some experience with common AT modem commands and if you know how to use MSComm6.0

Best wishes and good luck with testing.

Are you certain that you want to do all of that bit-twiddling?  I worked on fax send and receive for rockwell chipsets and it was a significant effort.

Would you ultimate need be satisified by a third-party package or by using the Windows Fax Service API?
