Description

The program on the PC should read data from the serial port, the readed data will then be transferred to a list in the programm,once in the list i can do with it what i want.

I'm really searching for the C++ code which is able to send a character to the port en on the other hand can read a character from the port. i thaught soemthin like i send for example an x, so long there is a x no data on the port , the controller receives de x and send a character to the port, the pc sees the x has been replaced and read the character sending another x the port (x is likely a character not found in de transmitting data)

something like that...
