o  cable faults

    Total number of times that the communications cable was detected
    as missing or invalid.

 o  creation time

    Time at which this entity was created.

 o  device errors

    Total number of times that a potential device error has been
    reported.

 o  framing errors

    Total number of framing errors detected on the line. This counter
    is not supported if the characteristic communications mode is
    synchronous.

 o  losses of carrier

    Total number of times that the carrier on the line was lost. This
    counter is maintained only if the characteristic modem control is
    none.

 o  losses of clock

    Total number of times that the transmit or receive clock was lost.

 o  outgoing call failures (Tru64 UNIX)

    Total number of times that an outgoing call failed to connect.

 o  rate fallbacks

    Number of times that the DTE changed from the high data rate to
    the low (alternate) rate. This counter is supported only if the
    characteristic modem options includes rate select, and if the
    characteristic modem control is full.

 o  test indications

    Number of times the DCE was put into test mode by the remote
    system. This counter is maintained only if the characteristic
    modem control is set to none.

 o  times cable detected

    Total number of times that a a valid communications cable was
    detected following a an error counted by the counter cable faults.

 o  times dce not ready

    Total number of times that a dce not ready event occurred. This
    counter is maintained only if the characteristic modem control is
    set to none.

 o  times reset (OpenVMS)

    Number of times that the data link client has performed a line
    reset.

 o  transmit enable timeouts

    Number of times the DCE failed to assert clear to send in response
    to request to send. This counter is maintained only if the
    characteristic modem control is set to none.
