4.10.1.4 X, Result Code Selection and Call Progress Monitoring Control
This command defines the data adaptor response set, and the CONNECT result code format. It determines whether or not the
g20 transmits particular result codes to the accessory. It also controls whether the g20 verifies the presence of dial tone when it
first goes off-hook to begin dialing, and whether engaged tone (busy signal) detection is enabled.
