Well, the terminal emulator doesn't have to be very sophisticated as
once the thing was running properly then you would use what ever the PC
system had installed.

The "two separate" would probably be easier to create but it occurs to
me that many PCs only have one serial line and the only serial line that
is common to all 11s is the console therefore only needing a single
