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.
