What is the speed of the oscillator on your IOBlix? If yours has a

config.
That's a good hint. It would explain the flashing modem LEDs,
although the
communication failed because of a bad clock.
I seem to remember having issues with the generated clock being
wrong... I fixed it, but perhaps I didn't commit the code. I think my
patches were similar to what's here:
https://mail-index.netbsd.org/port-amiga/2010/05/27/msg007401.html
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.
