I'm not sure exactly what you are asking. At the very least, you should obtain the following:



These manuals will show you what is inside the RS-232 pak and the bytes at which it receives and 
sends data: $FF68-$FF6B.

You might want to look at the NitrOS-9 code that communicates with /P and /T# as the RS-232 pak is 
used for both printing and terminal use.
scbbp.asm   for printing
scbbt.asm   for terminal use
sc6551.asm  driver
