            This code used when no other code is applicable.

            Additional vendor information may be available

            elsewhere.

               managementCommand:

            A management command terminated the call.  These

            commands include escaping to command mode, initiating

            dialing, restoring lines, and disconnecting.

               inactivityTimeout:

            The call was terminated because it was inactive for

            at the minimum duration specified.

               mnpIncompatibility:

            The modems are unable to resolve MNP protocol

            differences.

               protocolError:

            An error occured in one of protocol in use.  Further

            information is required to determine in which

            protocol the error occurred, and the exact nature of

            the error.

               powerLoss:

            The modem lost power and disconnected the call.

               equipmentFailure:

            The modem equipment failed.

               dtrDrop:

            DTR has been turned off while the modem is to

            disconnect on DTR drop. (Ref: V.58 cct108TurnedOff)

               noDialTone:

            If the modem is to monitor for call progress tones,

            but the modem has failed to detect dial tone while

            attempting to dial a number.

               lineBusy:

            Busy signal is detected while busy signal detection

            is enabled, or while the 'W' or '@' dial modifier is

            used. (Ref: V.58 engagedTone)

               noAnswer:

            The call was not answered.

               voiceDetected:

            A voice was detected on the call.

               carrierLost:

            Indicates that the modem has disconnected due to

            detection of loss of carrier.  In TIA-602, the S10

            register determines the time that loss of carrier

            must be detected before the modem disconnects.
