Kevin, 

I'm wondering if your modem and the SIO 1.60 are curiously in conflict over
the DOS session settings should you be running the BBS in DOS mode?  That
or possibly that the modem has an initialization setting for one of its
parameters that is in conflict?  Is it, for example, still depending on
non-hardware control?  Care to post any other information here and let me
think some more about this?  There are settings in SIO which can be used to
get at things that I might be able to help with should this be a problem..

Just trying to help still.
