Send and Rec to a serial port

[sekoon]

I am new to this programming stuff so please bare with me. I need to write a c# code that will allow me to send a single character string out one pin and receive it back on another. This will be used to tell me if a switch has changed from the opened to closed position. Any help would be appreciated. I am moving to the c#.net enviorment but that will be 4 weeks down the line here.

Thanks

Steve

I'm a bit fuzzy on how to actually use this project with my project. I'm using the Borland C# environment and I've added this project to mine. How do I launch the Confirm and Settings dialogs? How do I use classes from it?
