OK, thanks.
Many devices use pin 4 of the microUSB connector as a switching line (ex: cellphones use it to switch to OTG when pin 4 is grounded).
Maybe you could use that to route serial to the connector if pin 4 is pulled hi or low?? Just a thought.
Thanks

Would have done that but there are only two free GPIOs and looking at the layout they are pretty much impossible to route out. I'll try to think of something maybe involving the USB connector.
