Seems like it has 19 pins in a DE9 shell. That's a lot. VGA connectors were also in a DE9 shell, but had 15 pins.

The funny thing about the GRiD DE9 connector is that it's labeled "Serial", but every DE9 serial port connector I've ever seen is 9-pin. I have to wonder what else they are cramming into that 20-pin DE9 "serial" port.
