1) RS232 on ARM - used for FW debug
2) GPIO on FPGA - used for MIDI on some cores. Since it's just general purpose FPGA "legs" - it can be used as any double-wire interface including RS232.

I'd give it a go myself but as you previously mentioned the source is not available publicly so I can't even try .. This would be great to have this available (like it is on the Amiga and Atari ST cores) .. there are a number of us who could use this (with the previously mentioned TCPSER on a RasPi to connect to the outside world to connect to internet based Commodore BBSs -- yes they are out there even today!)
