When you're located in Europe it might make sense to contact one of the
hardware experts on a1k.org. They already fixed my A4000 and A1200 (new
capacitors, Lithium battery, etc.).

That's a good hint. It would explain the flashing modem LEDs, although the
communication failed because of a bad clock.

It wasn't comitted in com.c and meanwhile the code changed a lot. But
tsutsui added an "sc_frequency /= 4" in amiga/dev/com_supio.c, which should
do the same.

I doubt this is correct, as com_supio.c is also used by other serial boards
on the Amiga.
