No warranty for anything.You can find the protocol specifications athttp://www.garmin.com/support/commProtocol.htmlPlease keep in mind that most protocols are not implemented yet andtests can only done for the protocols supported by my Garmin Geko 201.This program uses /dev/ttyUSB0 as default serial port.You can override this by setting an environment variableLGGT_SERIAL_PORT with your serial port export LGGT_SERIAL_PORT="/dev/ttyUSB0"in bash or changing this line in main.c:char ttydevice[80]="/dev/ttyUSB0";Please report bugs, suggestions, ... to: dev-null@users.sourceforge.net
