Introduction

This chapter provides an overview of the serial port and describes the tasks involved in its configuration
includes the following sections:
• Serial port configuration task list
• Configuration tasks
• Examples
The V.35 standard is recommended for speeds up to 48 kbps, although in practice it is used successfully at 4
Mbps. The X.21 standard is recommended for data interfaces transmitting at rates up to 2 Mbps and is used
primarily in Europe and Japan.
The synchronous serial interface supports full-duplex operation and allows interconnection to various serial
network interface cards or equipment. Refer to the getting started guide included with your SmartWare for
specific information regarding the connector pinout and the selection of cables to connect with third-party
equipment.
Serial port configuration task list
Perform the tasks in the following sections to configure a synchronous serial interface:
• Disabling an interface (see
• Enabling an interface (see
• Configuring the serial encapsulation type (see
• Configuring the hardware port protocol (see
• Configuring the active clock edge (see
• Configuring the baudrate

Disabling an interface

Before you replace a compact serial cable or attach your SmartNode to other serial equipment, use the
command to disable the serial interfaces. This prevents anomalies and hardware faults. When you
shutdown
shut down an interface, it has the state CLOSED in the

Use the
figuration procedure.
