the connector is ground. The voltage between pin 2 and GND is 0 when the serial
port is off. Executing SERON should make pin 2 go to about 5V. I don't remember
if it's plus or minus, but that doesn't matter, it's the presence of a voltage when
the serial port is on.

Thank you Monte.
I’ll check that out and report back when I get home.
