BaudRate mismatch?
You need to match the settings on your to end points. This is almost certainly the result of wrong BaudRate (in fact, doubling or quadrupling it on the PC is likely to do the trick in this case).
The constructor you should use for your SerialPort object is SerialPort (String, Int32, Parity, Int32, StopBits) to clarify your settings. If you do a bit of programming against the serial port, you should use PortMon (www.sysinternals.com/Utilities/Portmon.html) or another port monitoring program (remember to start it before your own app). Remember that any program communicating via serial ports should do this in a seperate thread. Serial communication is higly blocking by nature.
"from my device to the PC": In this scenario, I have the best experience with 38400 baud, but higher might be fine, too.
Hope this helps
