lineSetLineDevStatus
The
lineSetLineDevStatus function sets the line device status. Except for basic parameter validation,
it is a straight pass-through to the service provider. The service provider
will send a LINE_LINEDEVSTATUS message to inform applications of the new state,
when set; TAPI does not synthesize these messages.
