we're still working trying to get Linux to communicate to our robot via an RS232 port. We added this code to the project in Mono:
Using System.Ports.IO SerialPort ports = new SerialPort("ttyS0",19200,Parity.None, 8, StopBits.One);
We can't get anything sent out of our COM ports. We're not even sure if we're coding it correctly. Is ttyS0 (we've tried S0-Sf) what we should be putting in the code? Please help!!
