Comand line tool usage: linux-uart-keyboard-emulation -c uart_port_name -s baud_rate Example: linux-uart-keyboard-emulation -c /dev/ttyUSB0 -s 230400 If you omit -c parameter, app use default uart port which is /dev/ttyUSB0. If you omit -s parameter, app use default baud rate which is 1000000. To start app without "daemonizing" use: linux-uart-keyboard-emulation -f which can be combined for -c and -s parameters To get app version use: linux-uart-keyboard-emulation -v (Fixing log error: stated: Version 1.1 +Linux executables should be: Version 1.2 +Linux executables )
