The feshell program contains an instruction set to control the gpsserver.

The interface GpsUnit and TCP/IP-based access to the is used to communicate with the gpsserver and to monitor the gpsclock. Use the feshell command "help gps" to find out more about the syntax of the commands.

GPS Clock commands:
 gpsserver [cmd] [unit] [debug] Start/Stop/Test gpsserver
 gpsstatus                      Display the status of the gpsclock
 gpstiming sec [n]              Get the timing of n seconds
 gpscapture [n]                 Display n captured time stamps
 gpsleapsec                     Get the number of leap seconds
 gpsinit                        Reset and initialize gpsclock
 gpsconnect [inifile]           Connect to the server
 gpsdisconnect                  Disconnect the gps server
 gpsset [par][arg]              Set parameter -> help gpsset
 ver                            Display the version number of the gpsserver

For the feshell command "gpsset" an extended help page is available.
