When Modem Manager answers a call, but no registered VTScada driver accepts it, Modem Manager hands the call off to the next application that handles incoming modem calls. If another application accepts the call, Modem Manager increments a count of concurrent handed-off calls. While this count equals MaxHandOffCount, no further calls are handed off.
If MaxHandOffCount is not defined, then there will be no restrictions on call hand offs.
