<p>Registers a handler for incoming shell commands. The function adds the shell command to the <code>compat</code> module. </p>
<p>The caller must initialize the <code>shell_cmd</code> structure with the command name and the pointer to the command handler. The caller must not free the memory for the command name string because the shell keeps a reference to the memory for internal use.</p>

<p>The <code>SHELL_MAX_COMPAT_COMMANDS</code> syscfg setting specifies the maximum number of shell commands that the <code>compat</code> module supports. This function aborts if the number of handlers registered exceeds this limit. You can increase the value for this setting.</p>
