Ulrich,
First, many thanks for all the delevopment you have done and share
freely. You and John Miles are both to be commended for so much of
this kind of work.
I have a Z3816A and tried your program. Seems it would need to be
updated to support this GPS receiver. I think it is pretty similar,
in commands, to the other Z38xx boxes. I wonder if you would be
willing to try adding support?
If you are willing to look at it, I have put some details in this
message. Feel free to contact me -- rexa at xertech.net -- if you need
more specifics or testing from my Z3816A.

There are some possible serial initialization issues. The help section
from GPSCon, describing this, can be found in the middle of this page:
http://www.realhamradio.com/GPS_Z3816A_Receiver.htm
(something odd happened with one of the pictures on that page.)
The command structure is very close to chapters 4 and 5 in this document:
http://www.leapsecond.com/museum/hp58540a/097-58540-01-iss-1.pdf
should be:
http://www.leapsecond.com/museum/hp58503a/097-58503-13-iss-1.pdf
with a similar description of the :SYST:COMM commands in this one:
http://www.leapsecond.com/museum/hp58540a/097-58540-01-iss-1.pdf
I used a serial terminal at 9600 baud to talk to my receiver and
capture the sequence below. I started with the 3816 serial interface
in FDUP (full duplex) mode so that the commands I sent show in the
capture. For normal communication it should be turned off, as I did
near the end.

Guys,
I have just uploaded a new version of Z38XX with the following
improvements:
1) Displays time AND date in the Nixie clock window
2) Knows how to read date & time from Jackson Labs receivers, so the the
clock window will function with them too.
3) Has a new "Manual Command Entry" which, well...., allows manual
command
entry. The combobox still needs to be filled with more presets but
you can
actually type in whatever you want. Note that the normal communication
thread is paused while this window is open. So close it whenever it
is not
used.
Enjoy
