Currently I am trying to use a Raspberry Pi to connect to the Amiga via a USB to Serial
That is a great idea.
maybe one day I'll get around to trying it over my bluetooth serial device.
I originally was trying to get it to connect to Windows back-end and never could get PPP to negotiate property and gave up after awhile.
