You may need to remove some bugs first.
That's not true. Serial cable can go for a
good many feet before

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.
