Hi guys,
I tune engine management systems on cars as a second job and I need a COM port on my X20. Is it possible to attach the connector to mainboard.
I need 3 wires only: Rx, Tx and GND (pins 2, 3 and 5 on RS232).

Any thoughts?

P.S. I'd stay away from USB-RS232 adapters as they cause many problems.

The PCMCIA cards from Quatech are supposed to be very good

If you could figure out the pinout for the dock connector, i think it would be possilble.

Quick measuring with DVM didn't reveal any pins that are directly connected to Rx, Tx or GND on Ultrabase X2....

Could someone have pinout for it?
