I have a programming question that I thought someone might be able to
help me out with.  I would like to be able to do some pre-processing
on characters that are to go out the modem port while using a
terminal program (say, versaterm or red ryder).  Is it possible for
me to "patch" the existing serial drivers, or perhaps intercept calls,
do my processing, and then pass the processed data on to the real
serial driver?  I have an SE, but would like this stuff to work on
all macs.  I have had a look around for the serial driver resources
using resedit, but haven't been able to find them anywhere on my
system.  All replies greatly appreciated.
