Your best bet is to use Bconin, Bconout and Bconstat.  Route all of
your RS232 out to a small set of routines which can be written for
any machine you want to run it on.  

This is what is done for FoReM ST and FoReM PC.  The ST version
uses the TOS RS232 driver (although fiddling with the buffers) and
FoReM PC uses the Greenleaf Communications library. Other than that,
the codes is 99.99% the same.
