I've got some equipment here that has RS422 serial

differential signal pairs rather than RS232's reference against ground.
Question is, can I wire up a cable so that I can use an RS232 terminal
with this RS422 equipment? (running over a short distance)
At the expense of stating the obivous, if this involved equipment I cared
about and my time meant something to me, I'd just buy a commercial
converter. Most feature some sort of isolation in addition to level
conversion. E-Pay shows several that run about $20 shipped.
