Initializing+Shell+commands

The command line interface is a traditional method for accessing the network functionality on a remote system (telnet), or in a device with a serial port (be that RS-232 or USB). A group of shell commands are available for µC/TCPIP. These may simply expedite evaluation of the network suite, or become part a primary method of access (or gathering debug information) in your final product.

Using the Shell Commands

To use shell commands some file, in addition to the generic µC/TCPIP files, must be included in the build:

See Directories and Files - Shell Commands

Using Network Interface Programming API

The following files must be included in any application or header files initialize µC/Shell or handle shell commands.

Include file	Description
Cmd/net_cmd.h	Contains the initialization function API

API Reference

All Interface APIs are presented in the section

Function Name	Description
NetCmd_Init()	Add Network Shell commands to µC/Shell

Initialization order

Modules must be initialized in the following order:

µC/Shell
Network suite (see Initializing Tasks and objects)
Network Shell Command
