Default Values
By default, the serial interface does not expect an inverted receive clock (rxclock).

This command applies to the NetVanta 1000R, 3000, and 4000 Series and Total Access 900 Seri es units.
Command History
Release 1.1 Command was introduced.
Functional Notes
If the serial interface cable is long, causing a phase shift in the data, the transmit clock can be inverted
using the invert txclock command (see invert txclock on page 681). This switches the phase of the clock,
which compensates for a long cable. If the transmit clock of the connected device is inverted, use the
invert rxclock command to configure the receiving interface appropriately.
Usage Examples
The following example configu res the serial interface to invert receive clock:
(config)#interface serial 1/1
(config-ser 1/1)#invert rxclock
