I give up! Where is this $5 USB-to-RS422 Adapter to be found?
Amazon has such a DTECH adapter for $22.
I am using a RS422-to-RS232 adapter and it has been totally reliable for
many years. I am not trying to use the pps output via the serial link so
any delay in the USB adapter would be irrelevant.
Is anyone successfully using a USB-to-RS422 adapter to communicate with
a HP Z3801A? How does the Z3801A software need to be configured for USB
or does the USB adapter simulate a RS232 port?
A lot was left unsaid in that simple statement below...

Paul and Hal, I think there may be some confusion here. I modified the
Z3801A to RS-232 way back when I first got it. My recent post was just
discussing some of what's in this demo/testing unit thing. It's just a
translator for TTL/RS-232 for when the GPS RX board (TTL serial) is
used by itself, hooked to a PC (RS-232), so the WinOncore SW can talk
to it. When the RX board is inside the Z3801A, it's controlled in that
environment.
These days, since PCs don't have serial ports, you can buy a RS422 USB
adapter for $5. If I were doing it now, I wouldn't bother reconfiguring.
