I am easily reading gps data on Com1(pin Di0). When I simply change the string in the SerialPort( “COM1”,4800) to SerialPort( “COM2”,4800)and connect the gps data to UEXT4 (COM2 RX (IN)), I am unable to receive the gps. What am I overlooking? Am I using the correct pin for COM2 receive?
I do not use handshaking.
