laptop% ./arduino-serial
Usage: arduino-serial -b -p [OPTIONS]
Options:
-h, --help Print this help message
-b, --baud=baudrate Baudrate (bps) of Arduino (default 9600)
-p, --port=serialport Serial port Arduino is connected to
-s, --send=string Send string to Arduino
-S, --sendline=string Send string with newline to Arduino
-r, --receive Receive string from Arduino & print it out
-n --num=num Send a number as a single byte
-F --flush Flush serial port buffers for fresh reading
-d --delay=millis Delay for specified milliseconds
-e --eolchar=char Specify EOL char for reads (default '\n')
-t --timeout=millis Timeout for reads in millisecs (default 5000)
-q --quiet Don't print out as much info
Note: Order is important. Set '-b' baudrate before opening port'-p'.
Used to make series of actions: '-d 2000 -s hello -d 100 -r'
means 'wait 2secs, send 'hello', wait 100msec, get reply'
