PowerSwitch toggle feature for the command line.
Posted: Tue Feb 23, 2010 4:39 pm
Hello everyone!
I needed a toggle function for powerswitch. So I played around with the code. I don't know if this is 100% correct but it Works. Any recommendations is more than welcome.
I added the option ./powerSwitch toggle <port> or ./powerSwitch toggle all.
The patch:
powerSwitch.c
