Hi Bob
Very many thanks for the prod re the Diagnostic port.
Considering the other GPS kit I talk to using Hyperterminal and the like,
often because there's no other option, I don't know why it's never occurred
to me to do the same with the Z3801As and now these..

When Satstat does the change, I’m sure it uses the correct command to do it.
The syntax is a phrase followed by a numeric. You then use the same phrase
followed by a question mark to see if it took it. The slave happy accepts the

Are you sure you've got the COM port set up correctly?

In SatStat, for example, you should get a message on startup that says

The bottom one referred to on Didier's site is the old Windows 3 version,

The later version is the one marked Satstat50, actually SatStat 5.0 and a
