Hi!
I am trying to read information from a PCB by using RS232 and a DB9 port. The PCB recieves data packages of 5 bytes and I have five different comandos (1 byte each) to send.
The comandos need to be in Hex code, how do I do to send these? do I need to send the comands together and how do I do that?
I have tried a couple of variations but nothing works..
