</blockquote><h4>AUTHENTICATION</h4><blockquote><p>
<p>

The VxWorks PPP implementation supports two separate user authentication
protocols: the Password Authentication Protocol (PAP) and the
Challenge-Handshake Authentication Protocol (CHAP).  If authentication is
required by either peer, it must be satisfactorily completed before the
PPP link becomes fully operational.  If authentication fails, the link
will be automatically terminated.
<p>
</blockquote><h4>EXAMPLES</h4><blockquote><p>
<p>
The following routine initializes a PPP interface that uses the
target's second serial port (<b>/tyCo/1</b>).  The local IP address is
90.0.0.1; the IP address of the remote peer is 90.0.0.10.  The baud
rate is the default rate for the <i>tty</i> device.  VJ compression
and authentication have been disabled, and LCP echo requests have been
enabled.
<p>
<pre>PPP_OPTIONS pppOpt;   /* PPP configuration options */

void routine ()
    {
    pppOpt.flags = OPT_PASSIVE_MODE | OPT_NO_PAP | OPT_NO_CHAP | OPT_NO_VJ;
    pppOpt.lcp_echo_interval = "30";
    pppOpt.lcp_echo_failure = "10";

    pppInit (0, "/tyCo/1", "90.0.0.1", "90.0.0.10", 0, &amp;pppOpt, NULL);
    }
</pre>

The following routine generates the same results as the previous example.
The difference is that the configuration options are obtained from
a file rather than a structure.
<p>
<pre>pppFile = "phobos:/tmp/ppp_options";  /* PPP configuration options file */

void routine ()
    {
    pppInit (0, "/tyCo/1", "90.0.0.1", "90.0.0.10", 0, NULL, pppFile);
    }
</pre>
where phobos:/tmp/ppp_options contains:
<p>
<pre>    passive
    no_pap
    no_chap
    no_vj
    lcp_echo_interval 30
    lcp_echo_failure 10
</pre>

</blockquote><h4>RETURNS</h4><blockquote><p>
<p>
OK, or ERROR if the PPP interface cannot be initialized because the
daemon task cannot be spawned or memory is insufficient.

</blockquote><h1><i>pppDelete</i>(&nbsp;)</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote>  
<p><strong><i>pppDelete</i>(&nbsp;)</strong> - delete a PPP network interface</p>

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>void pppDelete
    (
    int unit /* PPP interface unit number to delete */
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine deletes the Point-to-Point Protocol (PPP) network interface
specified by the unit number <i>unit</i>.
<p>
A Link Control Protocol (LCP) terminate request packet is sent to notify
the peer of the impending PPP link shut-down.  The associated serial
interface (<i>tty</i>) is then detached from the PPP driver, and the PPP interface
is deleted from the list of network interfaces.  Finally, all resources
associated with the PPP link are returned to the VxWorks system.
