C# COM ports in Linux

duki · 10-17-2008, 12:01 PM

Please Help!!!

We're trying to communicate through a COM port in Linux using C#. It was working great in windows because we just dragged over the COM toolbox option and configured it. Do we need to manually code the COM port in mono for Linux to use it?

Thanks!

Actually, high-level support for the serial port was conspicuously *lacking* in .Net until Microsoft introduced the "System.IO.Ports" namespace relatively late in the game (introduced in .Net 2.0, circa VS2005):

Anyway, you might be able to do anything you want simply by reading from and writing to "/dev/ttyS0".

Here's a good link on comm programming in general:

Ok we've gotten to the part of declaring a serial port as follows:

SerialPort port = new SerialPort("ttyS6",19200,Parity.None, 8, StopBits.One);

But we can't get it to send information out of the COMM. We've tried ttyS0-f with no luck. Any clue why it's not working? We've also tried /dev/ttyS0-f
