AND


Algorithm-Specific Ports
While the "a=" password argument is traditionally used to select the algorithm for a miner, an algorithm-specific port can also be used. Algorithm-specific ports cause miners which connect to those ports to be automatically assigned the algorithm associated with the port upon connection. The "a=" password argument can still be used to override the port's algorithm. The port assignments are the following:
