If the OS lets you use the serial or parallel port like a file, then you can do
something right now in a quasi-portable way.
Amiga OS has a special device named SER: (MS-DOS has COM1: and COM2: ?) and you can do
s: open/direct/binary %/ser
append s reduce [ "ATZ" (to-char 13) (to-char 10) ]
then 'pick s 1 char at a time, or better user 'read-io
There is a BIG problem however: if you ask more than the chars ready then you'll wait
forever (maybe 'wait [ s 0 ] will be the answer, but doesn't work right now with ports
open on files).
Ciao,
Daniele.
P.S. for Amiga REBOLs: thinking of SER: reminded me of SPEAK: (not so impressive as it
was 10 years ago, but REBOL could tell us when new mail arrives or a web page is
changed -- I know, it's platform specific)
