In the above data callback program, the phone number is dialed in the
DialSequence/EndDialSequence using the DialModem instruction. Any
needed re-dials are handled by EndDialSequence (DialSuccess).
LoggerNet recognizes the incoming call as a data callback by the arrival of the
“Public” and “Callback” strings sent by the SendVariables instruction in the
Table and Field parameters (visible in low-level log for ComPort). Callback
must be enabled in both the station and the ComPort screens.
The 25 second SendVariables timeout (2500 hundredths of a sec) allows the
slow phone connection time to build.
The program should be available for download from our website under
Support/Downloads/Program Examples.
