As far as I know, the Falcon has only one serial port. SCC-A is
hard-wired to the "LAN" connector here (while it can be switched to a
normal serial connector for the TT and Mega-STE). The code that I've
copied from Aranym does not fully support the SCC-A channel yet, so not
sure whether it makes sense to provide a "--scc-a" parameter already...
Let's focus on SCC-B for now which is way more important, since it is
the only serial port of the Falcon.

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:


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