That's not true. Serial cable can go for a good
many feet before
the signal breaks down (someone should pipe in with actual data ;)
450 feet at 9600 bps through multi strand sheilded cable. This was
between two buildings and ran through a drain to get under a road.
19200 bps was tried but was error prone. dropping the speed to 9600
bps worked.
