Abstract

A method and system for allowing a host processor and a modem to communicate both data and commands by multiplexing the information. In one embodiment, a connection between the computer system and the modem is established via a communication link. This step may further comprise opening a data channel and a command channel between the two devices. Next, data is encapsulated in a data frame with an indicator in the data frame that it comprises data. Then, a command is encapsulated in a command frame with an indicator that the frame comprises a command. Then, the data frame and the command frame are multiplexed to create a signal. Then, the signal is transferred over the communication link. In another embodiment, the commands are substantially compliant with the Hayes Standard AT Command Set (AT commands). In other embodiments, the computer system may be a portable computer system or a personal digital assistant. In another embodiment, the computer system is a portable electronic device, such as a cell phone, pager, or portable web-bowser.
