The file ythat actually does all the work is:
/etc/conf/pack.d/asy/space.c
if I remember correctly.  About 1.5 screens through the file is a 
listing of your tty ports - the i/o address is te first field,
interrupt (hardware) is the second and I believe the third
is the modem control field - if you want modem control, that
filed must be MCOUT2 or OUT2 instead of 0.  You should check
the file to be sure that they are correct - i've had my share of
problems with the initasy script that came with Esix.  (it doesn't
work for any other cnfig than perfectly "normal").
That's just a lead, and I don't know if it will work.
