    摘要： 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.

    摘要： A Cellular Data Network (CDN) identifies, collects and utilizes otherwise unused or unusable air time, in an existing Advanced Mobile Telephone System (AMPS). A Digital Cellular Overlay Network (DCON) is provided for performing CDN utilizing an underlying AMPS, where the DCON is transparent, with respect to the AMPS, and takes full advantage of existing AMPS equipment to keep the cost of performing CDN to a minimum. The resulting digital network may be used for high speed non-interfering data communications, i.e., data communications that do not degrade the underlying system's capacity and capability (qualitatively) to handle voice traffic. Expanded use of well-known radio control signals, in particular "busy bits" and "dotting sequences," provides a DCON capable of performing CDN in both a reliable and flexible manner.
