Anyway, go the safe route and use the real serial port for now. There's at least 2 projects in early stages that could lead to multiple serial ports being available. Chimera is looking at a USB based extender that will hopefully allow USB<->serial dongles to be used with the empeg, and I'm about 75% done on a pcb design to muliplex the serial port into something more useful (including OBDII and Oncore support). I got stalled over Christmas, but hope to get cracking again soon.

If anyone out there is a PIC expert and wants to help, please weigh in..
