I don't know much about which drivers are still in active use. People
don't really
tell me ;-)

FWIW, if I use my Amiga's serial port, it's just for a serial console, in case
all else fails (last time I needed that was several years ago).

We have 3 "classes" of serial drivers:

- generic_serial-based:

o MVME147_SCC
o MVME162_SCC
o BVME6000_SCC
o A2232

All of these were marked BROKEN lately due to generic_serial,
while there's even a
new ATARI_SCC under "active" development...

- plain drivers/char:

o SERIAL167
o AMIGA_BUILTIN_SERIAL

- drivers/serial:

o SERIAL_PMACZILOG (Mac)

Sun 3/3x support might be (re)added to SERIAL_SUNZILOG

Funny... so "fortunately" we never found time to move the m68k serial drivers
to driver/serial/? Long live procrastination ;-)
