A.4.2 DialModem Example (for CR1000)

The program below does 2-minute callbacks via the COM220 configured for SDC7. DialModem is set equal to a variable, so that the success/failure result can be used by the EndDialSequence instruction. If the call fails, the link will be terminated at the EndDialSequence instruction. If the call is successful, the device will be kept on-line until the SendVariables command is completed.

Note, that for data callbacks to occur, callback enable must be selected in

LoggerNet Setup both for the comport and for the datalogger.
