I have been told to develop a virtual com port so an app the company has can read off com "comCompanyNameV1".. I tried to pick apart com0com, but it seem so incomplete I'm finding I have to kludge around large parts of it and I have yet to get anything to come close to compiling. Mostly because the tools that are outlined to use to build aren't available anymore.

Can anyone point me in a direction to allow me to create a virtual com port that? I really don't want to have to spend a month trying to figure out how to do it from scratch.

Oh.. if some knows how to get it done in languages other than c++ I'm good with that too.

I forgot to mention. The actual hardware might be attached to com1 but I still have to have the app read on the custom named com. It's a third party app and we've got no idea why they picked a strange named com, but they did.

Does How to create a Virtual Com1 port in windows? help at all?

This is a link to SDK that may make it easier - http://www.download32.com/virtual-serial-port-sdk-i11199.html

In reply to your comments. Its been a long time since I did anything with the DDK but googling indicates that there may be a serial port example in there. I cannot be certain. However logically speaking the virtual com port should be an NT entity with a user mode component (already supplied). So I'd suspect you'd write a kernel driver that would then communicate with the USER mode process as you see fit.

  • No, the other questioncame up in my search.. There isn't really an answer on that question. The other link is a pay-for kind of thing. I think the reason for me having to do it was to avoid licensing issues, and to make sure we have more control over it than most third party software give. – baash05 Jun 23 '09 at 23:26
  • I found this document. It tells me what the samples are with the DDK install. http://www.osronline.com/ddkx/gstart/gs_design_9lk7.htm – baash05 Jun 24 '09 at 03:54
  • That's way old. Download the latest and see. – Preet Sangha Jun 24 '09 at 20:29
  • It seems odd to me that all the samples would be built with a make file.. Is that right to you? I would figure it would integrate with VS. I would sorely love a project I could open.. Oh and to winge a bit. I wish coders would put more value on commenting their code. Especially when it's set to be open source. (for those that don't) – baash05 Jun 25 '09 at 03:31
  • Nope. (in my day lol :) Drivers were always built with with make and build. You can see http://stackoverflow.com/questions/1037343/how-can-i-build-a-driver-using-visual-studio as to how to make it work with VS. – Preet Sangha Jun 25 '09 at 09:41
