It'll handle way more than its spec calls for. When researching the
content for "RS232 Solution", Joe Campbell ran it through a couple of
thousand feet of wire (on a spool). Well, I guess that by being on a
spool, the two ends were less than 10 feet apart. :-)


The original IBM PC Parallel Printer Port was the one that was spec'ed at
10 feet (3 meters). I often ran 30 feet with it.
I have no idea what the spec is for 1284.
