Well, if your bridgeboard is up and running, then you can communicate
with all stuff on the PC/AT side by means of the functions provided by
the Janus library (on Amiga and PC side).

If you don't have a bridgeboard, the busses are completely separated,
you have ONLY power supply on the PC/AT slots. But as far as I know
there may exist one (some?) Amiga card(s) that connects the Amiga bus
with the PC bus and makes the latter accessible for I/O. But don't
know any details or producers, sorry. But I'm sure these I/O addresses
are in the end different from their situation in a PC, so access by
SoftPC wpuld be at least questionable.
