| Description | This value represents the Physical Link hardware clock
mode for the line device. The values for clock-mode are:
INTERNAL For software controllable loopback use of
the clock. On those devices that can support this
mode, it causes the device to supply a clock signal
such that a transmitted messages can be looped
back from outside the device. This may require manual
intervention other than the setting of this parameter
value. For example, the operator may have to connect
a loopback plug in place of the normal line.
EXTERNAL For normal clock operating mode, where the
clock signal is supplied externally to the controller.
Note that these values are incremented by one compared to
the standard DECnet values. |
