Abstract

A method for wireless data transmission for adaptive multiple protocols is disclosed. In one embodiment, data is collected by a data collecting devices and transmitted to one or more Cellular Digital Packet Data (“CDPD”) modems via one or more RS232 interfaces. Applications programs in the CDPD initiate communications and transmission of serial data begins when the status of both interfaces is established. Transmission of information as serial data via RS232 interfaces minimizes the resources required to communicate data between different devices using different standards and protocols.
