METHOD AND SYSTEM FOR DIAGNOSIS AND CONTROL OF MACHINES USING CONNECTIONLESS MODES HAVING DELIVERY MONITORING AND AN ALTERNATE COMMUNICATION MODE
First Claim
1. A method of controlling communications, comprising:
- automatically generating, by a first monitored device, a first message;
automatically transmitting, from the first monitored device, the first message to a second monitoring device using a first mode of communication;
monitoring, by the first monitored device, whether the second monitoring device transmits, to the first monitored device, a response to the first message; and
transmitting, by the first monitored device, a second message to the second monitoring device using a second mode of communication when the step of monitoring determines that the first monitored device has not received a response to the first message from the second monitoring device, wherein the first monitored device is one of a printer, a facsimile machine, a facsimile server, a scanner, a copier, a metering system, and a vending machine.

Abstract
A method and system for retransmitting messages using an alternate mode of communication when an original mode of communication is determined to be unsuccessful. A message is first transmitted using a connectionless-mode of communication such as by using an Internet electronic mail message. A request for acknowledgment of receipt of the message and/or individual operators within the message is requested. If the acknowledgment of receipt of the message is not received within an appropriate time determined based on an urgency level of the reply, the message is retransmitted using a more reliable mode of communication such as a connection-mode of operation which includes a direct telephone connection over a public telephone network using a modem, using an ISDN line, or a cable with a cable modem.

15. A system for controlling communications, comprising:
-
means for automatically generating, by a first monitored device, a first message;
means for automatically transmitting, from the first monitored device, the first message to a second monitoring device using a first mode of communication;
means for monitoring, by the first monitored device, whether the second monitoring device transmits, to the first monitored device, a response to the first message; and
means for transmitting, by the first monitored device, a second message to the second monitoring device using a second mode of communication when the means for monitoring determines that the first monitored device has not received a response to the first message from the second monitoring device, wherein the first monitored device is one of a printer, a facsimile machine, a facsimile server, a scanner, a copier, a metering system, and a vending machine.
