A.4.1 ModemCallback Example (for CR1000)
The ModemCallBack instruction is available in the CR1000 with operating
system std.12 or greater, in the CR3000 with operating system std.05 or
greater, and in the CR800 or CR850 with operating system std.03 or greater.
The following program uses the ModemCallBack instruction to call LoggerNet
every 2 minutes. The ModemCallBack instruction assumes that LoggerNet
resides at the phone number and that callback is enabled in LoggerNet Setup,
both for the comport and for the datalogger.
