Thread: Serial port reading

I'm trying to make a program in C# that reads some characters from an external device attached to serial port. I've looked in MSDN but I couldn't figure out anything. It seems to be complicated because of all the multithreading and multitasking in Windows. I just need to read several characters that are sent periodically (e.g every 5sec) from a device. Help, please...

I've never tried what you are asking, but you might find this a little interesting: http://msdn.microsoft.com/coding4fun...e/default.aspx
