Rex,
I measured them attached to a valid RS-232 port. I am dismantling the unit and I will be checking the voltages right at
the chip.

Matt,
It's been modified. I was told that when I bought it, and confirmed it myself. I don't get the right voltages; I
need a new RS-232 interface chip.

I never heard an answer about if you had measured the voltages at the Z3801A connector open circuit (nothing attached
that could be loading or driving what you are measuring).
