Can you specify Antminer overclock settings in bfgminer config file? I've just started upgrading my USB miners with Antminer U2's and so far everything is running well.  I am able to run all of my miners OC'd to 2.0GH/s with the following command:

bfgminer --set-device antminer:clock=x0981 -o POOL_URL -u POOL_USERNAME -p POOL_PASSWORD -S antminer:all

However I would like to know if it is possible to specify these overclock settings in a config file... I normally have a config file with various options set up that I load using bfgminer's -c flag.  I tried the obvious:


...
"shares" : "0",
"kernel-path" : "/usr/local/share/bfgminer",
"scan" : [
        "antminer:clock=x0781@/dev/ttyUSB0",
        "antminer:clock=x0781@/dev/ttyUSB1",
        "antminer:clock=x0781@/dev/ttyUSB2",
        "antminer:clock=x0781@/dev/ttyUSB3",
        "antminer:clock=x0781@/dev/ttyUSB4"
]
}


but unfortunately that didn't work.  Also my attempts at googling
I found plenty of examples of people setting overclocking using the command line (or batch files) but none using a config file.
Try:

"scan" : [
        "antminer:clock=x0781"
]
