5 # linux (plug in the avrusb500 and type dmesg to see which device it is):
6 LOADCMD=avrdude -P /dev/ttyUSB0
8 # mac (plug in the programer and use ls /dev/tty.usbserial* to get the name):
9 #LOADCMD=avrdude -P /dev/tty.usbserial-A9006MOb
11 # windows (check which com-port you get when you plugin the avrusb500):
12 #LOADCMD=avrdude -P COM4
14 # All operating systems: if you have set the default_serial paramter
15 # in your avrdude.conf file correctly then you can just use this
16 # and you don't need the above -P option:
