Thanks for your helpful comments and the notes from everyone else.  Yes, I do
try to read the documentation, although I have never used "man" as I prefer to
read from the Web on a separate display.

You ask why - several people have asked for this!

I had forgotten the -G switch, although in this case it isn't required as
u-center doesn't connect or doesn't recognise udp/tcp on 2947.

gpspipe -r gives me just what I want, and it was then a matter of understanding
"nc" to make it serve that outgoing data over a connection.

I ended up with a very simple script:

   gpspipe -r | nc -l 12101

Then on u-center configure a connection:

   Receiver, Connection, Network connection: tcp://

Works nicely!

   port 12101 was chosen at random is the address of the Raspberry Pi serving the data
