It really depends on the cable.
I tried a 5m serial cable two weeks ago ; I only got garbage at the
end. It was one of those flat 2 pairs cable (like a telephone cable).

RS-485 is the go now over RS-422... Much harder to find RS-422
converter these days, while a 485 can be found on ebay for $5
RS485 theorical is 1200m..
