Yeah Dave,
That's correct, but one thing to be careful of, RS232 cables are often
pinned differently from one end to the other,as you would have data out
from unit "A" to data in on unit"B" and visa-versa....in other words
pin three on the left end would show continuity to pin two on the right
end so you might have to "ring out" the cable with a VOM to make sure
your data is heading in the right direction..
