Yo Gary,

many thanks for your support.

There is maybe a minor typo but probably I don't understand. In the 
section "Survey-In and RTCM Prerequisites" one can read at the end:

If your receiver responds to neither request, then you can use Survey-in.

Shouldn't it be

.... then you can't use Survey-in.

Or how is it to understand ?

Yes, maybe I want. But not now, later in the year.There are other things 
to learn.

Ok, my question was not well done. Sorry for my English. The question is 
if "ubxtool" is communicating with the program "gpsd" or if it's 
directly communicating with the module. But last possibility I can't 
imagine because the only way is in my case /dev/serial0 and this is 
occupied by gpsd.

Actually this question is not necessary. Reading the man page I see: It 
can read and write directly through a serial device, or through a 
running gpsd instance

In this case synopsis of the man page is not complete.

also this bracket is wrong: ubxtool [OPTIONS} [server[:port[:device]]]

instead of } should be ]

I took a look into gpscsv. Looks promising for my ideas.


Kind regards
