Re: Monitor a line without ownership possible?

Unimodem (and possibly other TSPs) don't provide events to monitor
only applications if no other application has the line open with owner
privileges. This was done so that TAPI wouldn't take the com device
associated with the modem and prevent non-TAPI apps from accessing the
modem.

Most "normal" TSPs can report call events to monitor only apps
irrespective of any other Owner apps running or not.
