duplex
Syntax duplex {half | full}
Context config>port>serial>rs232
config>port>serial>v35
config>port>serial>x21
Description This command configures the duplex mode. Half-duplex mode uses a single transmission
path.
Full-duplex mode uses two independent transmission paths, one in each direction, allowing
two connected devices to transmit and receive data simultaneously.
Half-duplex mode is not user-selectable; an error message is displayed if this option is
selected. Half-duplex mode is selected automatically if multidrop data bridge (multi-drop) is
configured in slave mode (applies to RS-232 only).
Default full
Parameters half — uses a single transmission path
full — uses two independent transmission paths, one in each direction
hold-time
Syntax hold-time {[up hold-time-up] [down hold-time-down]}
no hold-time
Context config>port>serial>rs232
config>port>serial>v35
config>port>serial>x21
Description This command configures the serial link dampening timers in 100s of milliseconds, which
guards against reporting excessive interface transitions. Once implemented, subsequent
transitions of the interface from one state to another are not advertised to upper layer
protocols until the configured timer has expired.
Default no hold-time
Parameters hold-time-up — the hold-timer for link-up event dampening. A value of zero (0) indicates
that an up transition is reported immediately.
Values 0 to 100 (in 100 ms)
hold-time-down — the hold-timer for link-down event dampening. A value of zero (0)
indicates that a down transition is reported immediately.
Values 0 to 100 (in 100 ms)
