The present invention first provides a local mode in order to provide a monitor function in a remote communication device. The determination of whether or not the local mode is 42 may send and receive a 'keep alive' message to the local port, and the local mode. Recognize that the operation in the local mode (43).

Operation 43 of the local mode is the same as that of the modem mode, but is switched to the HDLC mode 45 when the keep alive time out 44 is reached.

In HDLC mode 45, packets received through the HDLC port are processed and operated accordingly. In the HDLC mode 45, the DSR (Data Set Ready) of the modem is always monitored. When the modem is connected, the modem mode is switched to the modem mode to perform a command received through the modem (47) and operate accordingly. When the DSR becomes '0' or 'Keep alive time out' occurs, the modem disconnects and returns to HDLC mode 45. In the HDLC mode 45, when a message is received by monitoring a ring of the pager (50), the message is analyzed and the corresponding operation 51 is performed, and then the process returns to the HDLC mode 45.
