To save space, there could be a radiobox for which one of them is
emulated, as user is unlikely to need multiple ports at the same time:
----------------------------------------
Enable RS232 serial port emulation for:
(x) MFP ( ) SCC-B
Write <port> output to file:
___________________________ [Browse]
Read <port> input from file:
___________________________ [Browse]
----------------------------------------
Where <port> changes based on selected radiobutton (if SDL GUI gets note
of those changes).
But currently Hatari does not emulate SCC-B input, so that would also be
misleading...
I would be totally OK if you just shade out the input prompt, who needs RS232 anyway. :D
While we are at the topic, I find it quite annoying that I have to select an existing file for both input and output. I get it - the idea was to select a real Linux device but if you just want a stupid file redirect... I have to create two empty files from which one isn't even used. Otherwise Hatari disables the redirection completely, even if I miss just one (input) file path.
