I searched but could not find a way to configure PhoenixMiner in AwesomeMiner to change the proto setting from its default. (I need to be able to change setting of proto from 2 to 3.)
If I use the command line parameters field, the AwesomeMiner program is unable to monitor the statistics of PhoenixMiner and the state of the GPU. (i.e. It says "Interface Offline")
The idea is that you can go to the Properties dialog for your pools, and go to the Claymore section (yes, Phoenix Miner shares the same concept, but I will rename this one) and add a property "PROTO" with value 3. However, when testing this concept I do see that it only works for overriding the proto-flag set by Awesome Miner for Nicehash and MPH. In the next version of Awesome Miner I will make a change so you can override this on any pool.
