Have posted my JustinIO.cs at http://www.gotdotnet.com , it is a very simple wrapper around the win32 blocking file I/O for using the comm ports, I wrote it back in PDC Release days. I have seen it modified to use parallel ports as well. It should get you started, although most of the inquiries I get on it seem to be a lack of understanding how to write non-event based I/O. So be warned its not like MSComm, if you want events/non-blocking I/O you have to write that yourself around my code. There are also some other P/Invoke based samples out there, I think one even implements a stream out of the serial port, and another is based in VB.Net.

I've tried to open a filestream using COM1 as the target with no success. In desperation I've resorted to using MSCOMM32 to do the comms for the small project we had to get completed. Is there another way that anyone knows of?? thanks. You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
