Control the modes of an iTrax GPS
itraxctl
-n
-b
-s speed
serial-port
DESCRIPTION
itraxctl switches an iTrax GPS to NMEA
or iTalk Binary mode. Port speed and protocol can be set independently of
each other.
You will probably need to be root to run this program, as the
serial device it uses is normally privileged.
The program accepts the following options:
-b
Force GPS into binary mode. This option overrides any previous
-n options.
-n
Force GPS into NMEA mode. This option overrides any previous
-b options.
-s
Set port speed. iTrax chipsets support speeds of 4.8 - 921.6 kbps
though the *NIX drivers might not run faster than 230.4 kbps. Fastrax
recommends that a serial port not be run slower than 115.2 kbps when the
iTalk protocol is selected.
BUGS AND LIMITATIONS
Setting NMEA mode from binary mode does not yet work. This is being
actively investigated. Integrated data logging control is planned but not
yet supported.
