A method and system are disclosed for permitting selected command sequences to be processed by a modem during data transfer operations. A preselected escape character is designated and inserted into a data stream to be applied to a modem in order to identify a selected command sequence which follows. A termination character is inserted into the data stream following the selected command sequence. Upon detection of the preselected escape character, the selected command sequence is coupled to a command processor within the modem and processed. In applications in which the modem is coupled between a data processing system and a cellular telephone communication channel, the selected command sequence may be utilized to transmit communication channel parameter status queries to a cellular telephone associated with the modem. In this manner, the Received Signal Strength Indicator (RSSI), bit error rate, or other indications of communication channel status may be queried. An identical technique may be utilized to transmit a response to each such query to the data processing system, permitting real time display of cellular communication channel status information during data transfer.
