In that case it could be more user-friendly if the file options
would talk about ports instead of Atari internal chips.

I.e. with these:

  --rs232-in <file>  Enable serial port, use <file> as input device
  --rs232-out <file> Enable serial port, use <file> as output device

being wired on Falcon to SCC-B, and to MFP-1 everywhere else.


With MegaSTE/TT eventually supporting additionally:

--rs232-2-in
--rs232-2-out
--rs232-3-in
--rs232-3-out
--rs232-4-in
--rs232-5-out

And those being mapped to MFP-2, SCC-A, SCC-B as explained
in the documentation.

Opinions?
