Hi beginner,

 

how do you connect a GPIB device using a RS232 cable with your computer? Those are two different connectors/cables...

Hi beginner,

 

does your "PCB" actually has a COM port - or did you connect just some wires to some pins?

 

Did you test your serial connection with HyperTerm? Using correct port settings?
