When I setup a GPS receiver, I try to remember to write down the recipe. (and enough notes to remind me what/why) Then I can cut-paste from one window looking at my notes to another shell window. I've had reasonable luck with things like: stty --file=/dev/ttyUSB1 4800 cat /dev/ttyUSB1 # to see what it's sending # \$PSRF103,0,0,0,1*24\r\n Turn off GGA echo -e -n "\$PSRF103,0,0,0,1*24\r\n" > /dev/ttyUSB1 That particular unit needs a valid checksum on commands so the *24 is required. We should collect this stuff on the wiki. -- These are my opinions, not necessarily my employer's.
