The port seems to be configured to 115 kbps on my device, and connects to /dev/ttymxc0 on my device.
There is one more /dev/ttymxc port active, which seems to be used for the bluetooth interface in the T68.

Nice, thanks! The next week I will solder the pins on that header and try to figure out something!
