Dear All,

Am developing a small program where it reads a message from a serial port and forward it to another serial port. It sounds simple; however, am finding diffuculities.

To test my code, I use a Terminal to enter a message in one of my serial ports and it should read the message but in my case it doesn't.

I use serXread() function which it should read my message and write it to the port then forward it. But nothing!

When I use serXputc('A') in my code, my serial port reads it. So nothing is wrong with my ports, but is serXread wrong?

So, my question, is there any other function i can use to read a message in a serial port? any advices?

Thank you!

This is a part of my code:


  //If a message is sent to the terminal to port B, it wont read it or write it to it!
  n = serBread(s, 15, 20);

  //the port reads 'A' as shown in the Terminal

   }//end costate1

}//end while_2
