Chapter 8 Configuring the Serial Interface

Configuration Examples

Low-Speed Serial Interface: Examples

The section includes the following configuration examples for low-speed serial interfaces:

•Synchronous or Asynchronous Mode: Examples, page 8-20

•Half-Duplex Timers: Example, page 8-20

Synchronous or Asynchronous Mode: Examples

The following example shows how to change a low-speed serial interface from synchronous to asynchronous mode:

interface serial 2 physical-layer async

The following examples show how to change a low-speed serial interface from asynchronous mode back to its default synchronous mode:

interface serial 2 physical-layer sync

or

interface serial 2 no physical-layer

The following example shows some typical asynchronous interface configuration commands:

interface serial 2 physical-layer async

ip address 10.0.0.2 255.0.0.0 async default ip address 10.0.0.1 async mode dedicated

async default routing

The following example shows some typical synchronous serial interface configuration commands available when the interface is in synchronous mode:

interface serial 2 physical-layer sync

ip address 10.0.0.2 255.0.0.0 no keepalive

ignore-dcd nrzi-encoding no shutdown

Half-Duplex Timers: Example

The following example shows how to set the cts-delay timer to 1234 ms and the transmit-delay timer to

50 ms:

interface serial 2

half-duplex timer cts-delay 1234 half-duplex timer transmit-delay 50
