[Coco] USB to serial cable

[Arthur Flexser]

There's actually a shorter way to disable the CD check that requires
just 4 pokes and doesn't need a ROM-to-RAM copy routine:

POKE &HFF23,&H30
POKE &HFF22,&HF9
POKE &HFF23,&H34
POKE &HFF22,0

This reprograms the PIA bit for CD detection to be an output rather
than an input, and then sets the bit to the proper value so that the
CoCo always sees CD as present..
