I need a program (or .VXD), in C, that will capture the parallel ports, so that when a DOS program (running in a DOS box) sends data to a parallel port, to save this data in a file.I also want the complete sources. I am willing to pay a small amount of money for this, but I want to test it
to be sure that it is working.
I am waiting for your offers.

You can do it in another way - buy a parallel to serial converter
(I don;t think it more then $20) and use any terminal program to capture from serial port

I have it. Utility called PRN2FILE with ASM source. Is it OK for you ? I can send it by e-mail.

Is it a TSR or a Windows 95 program ? Anyway I would like to test the executable under Windows 95, and if it works you send me the code. By the way the code is yours ?

1) It is TSR.
2) Code not tested under Win95. But when you run DOS program, it'll
 capture output. Win95 driver uses direct printer port access, so
 no capture is possible.
3) Code is not mine. So I can send it in one archive (ARC file,
 ~20K in size).

Uhh, to send it, I need your e-mail address.

My e-mail address is inca@incahellas.com , but I doubt it will work, because I have at least 5 other TSRs and none worked correctly.

OK. PRN2FILE on the way. And you can just reject my answer, if it
not suit your needs.

Thank you but I cannot decompress ARC files. Can you send the files again, after you decompress it?

I'm sorry but PRN2FILE did not work. When I print to lpt1 (e.g. dir>LPT1) it says "Write fault error writing device LPT1
Abort, Retry, Ignore, Fail?". When I print to lpt2 (which does not exist) it says: "The computer name specified in the network path cannot be located."

Can you tell me sequence of your actions ?
You opened DOS box, loaded PRN2FILE.COM and tried to print ?
Or somehow else ?
