Send character to serial port

Question

I would like to send the character 'a' to the serial port.

I tried:

serialPort1.WriteLine("a");

but it's not actually sending the character 'a' to my board.

Any ideas?

Answer 1

Are you using the serial port class?

Answer 2

How do you know that it isn't sending the character? Is it possible that the baud/word length/parity setting are off and your board is just not recognizing the character?

Also, why c#? Just seems an odd choice for hardware IO.
