That does sound very odd if it is RS232.

Have you measured these voltages out of the Z38xx unit into just an open 
cable? That would take any driving or loading from the PC-end serial 
port out of the measurement.

BTW. Last I read here, you seemed to now think that you actually have a 
Z3801A. If that is correct, maybe it would be nice to start a new thread 
with a proper heading to reduce confusion for anyone searching the 
archives in the future.
