Sierra Wireless EM 74xx modems come with a serial port outputting NMEA-0183 GPS sentences. In order to make it work, the magic string '$GPS_START' needs to be written to the modem, as only then the modem firmware starts sending NMEA-0183 output. Add option 'sierragpsstart' which if set to anything else than 0 will make kplex send the magic string when the device is opened.

Sierra Wireless modems need the string '$GPS_START' to be sent to the GPS tty device as only then the modem firmware starts emitting NMEA-0183 sentences. Add an option 'sierragpsstart' to kplex' serial driver to support that quirk as kplex can be very useful to spread GPS data over the network while also supplying 'ugps' using a PTY, allowing for correct system time to be set automatically on boot up from GPS. This patch is also PR'ed at the upstream project: stripydog/kplex#54 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
