Abstract: First and second data processing terminals (12, 28) are coupled together via at least one modem (36). A stream of data is supplied to the modem, which has a data transfer mode and a command mode while that modem is operating in the data transfer mode in a first communication session. A preselected escape character followed by a selected command sequence is inserted into the data stream and is detected and utilized by the modem to automatically initiate a second communication session by specifying the network, node, application, service level and the like for the second communication session. Thereafter, selected data within the data stream may be preceded by the preselected escape character and a session identification command sequence and thereby accurately identified as associated with a particular communication session, without requiring the data processing terminal application to have knowledge of data packet protocols and formats.
