Hello. I am a bit new to the .NET environment, and though I feel I was able to get a good handle on most of the basics of .NET, I believe I've encountered a problem beyond the basics. I am trying to talk with a device called a ColorPAL that uses
asynchronous serial communication, but it is half-duplex instead of full-duplex. I am able to send it the hex string commands that it wants just fine with the TX line. However, I find myself unable to read because the RX isn't connected to anything.
Basically what I want to do is that I want to be able to swap the TX line to become a RX line so that I can then read line of the half-duplex. I read that there is a PinChanged event, so it lead me to believe there is a way to change pins??
If the RX line is very high impedance I could connect it to the TX line, but I have no idea about that.
How can I get a full duplex to read a half-duplex using the visual studio software?
Here is the code I'm using, in case that helps.
using namespace System;
