Embodiments include systems and methods of controlling access to radio access protocol stacks within a communication device using a single parameter command. A processor of a communication device may send to a modem an attention (AT) parameter command that includes a parameter identifying two or more protocol stacks from among a plurality of protocol stacks of the communication device. The modem may use the included parameter to identify the protocol stacks from which modem information is to be obtained, and access the information indicated in the AT parameter command. The processor may receive from the modem information related to each of the two or more protocol stacks identified in the parameter included in the AT parameter command.
