I'm tiring of using a terminal to put my Kenwood radios' TNCs into kiss mode. Here's a oneliner in python that will do the same thing. Why Python? My experience with Ruby and the satpack code was that its serial library was hard to get going on windows. This should be more portable, and get the job done:
python -c 'import serial;ser=serial.Serial("/dev/ttyUSB0", 9600, timeout=1);ser.write("kiss on\r\n");print ser.readlines();ser.write("restart\r\n");print ser.readlines();'
It should reply something like this:
['kiss on\r\n', 'KISS was OFF\r\n', 'cmd:']
