Unlike GSM cellphones, where commands are specified in a publicly available standard, each CDMA vendor seems to roll its own. So far I've found no AT commands that manipulate the internal phone book or provide access to SMS messages. The cellphone just returns the contents of whatever address is requested - no fancy business that might distract the cellphone from its prime directive. Lacking a Rosetta Stone, that's all I can figure for now. He'd particularly like somebody who recognizes the flag bytes in the binary protocol to point him toward some details in that area.
