Under Unix (in general), you can use the termios package.  This
is ugly, but it works and is moderately portable between Posix
systems.  If you want a nicer wrapper around the termios stuff,
there are two PosixSerial packages.  The one I wrote and has
undergone minimal testing and has no documentation:

I've seen references to another module named PosixSerial. But,
the last time I saw it mentioned nobody had a valid location
for it.
