Run a 'grep' in the background reading the serial port looking for proprietary MTK commands. In this case it's process 19177. Send a command -- PMTK605 -- the output is printed -- PMTK705. Bring the grep to the foreground and press control-c. # grep 'PMTK' /dev/ttyO4 & [1] 19177 # printf "\$PMTK605*31\r\n" > /dev/ttyO4 # $PMTK705,AXN_2.10_3339_2012072601,5223,PA6H,1.0*6A # fg grep 'PMTK' /dev/ttyO4 ^C # You can also turn off NMEA sentences and use a terminal program to talk to the GPS. Naturally I don't recommend any of this because it can fail in many ways. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
