An improved radio modem is disclosed for use with an autonomous radio telemetry system. The radio modem includes a reprogrammable microprocessor, a radio transceiver, and a serial interface. By providing a software program within the radio modem that converts the serial interface into a general purpose interface to external input/output devices, and by providing additional programmed decision making capability into the radio modem, no external telemetry computer is required to interface with the input/output devices, and the radio modem operates as a combination telemetry computer and radio device. The radio modem also includes a novel reprogrammable state machine architecture for communicating with the input/output devices, and for deciding what actions to take based on the status of the external devices.
