A wireless data device (512) having a processor (530) and a computer program that is structured according to a protocol stack model. The program has application layer (11), session layer (21) and transport layer (31) communication program modules. The transport layer communications program module (31) has a connection identification number assignment step (301), at least first and second transmission program modules (e.g. 310 and 316, 326 or 328). A decision element (310) is coupled to the connection identification assignemt program element and the first and second transmission program modules for routing communications to one of those program modules. Also provided is a method of communicating via one of a first relatively rich communications protocol and a second relatively bare communications protocol. When routing communications to a transmission program module for the relatively bare protocol, communications are preprocessed in a supplementary functional module. |
