                     18: <p>This chapter describes commands that configure the Encryption Control
                     19: Protocol (ECP) layer. All of these commands apply to the currently
                     20: active bundle.</p>
                     21: <p>To use ECP you should enable encryption at the bundle level.
                     22: To allow encryption to be negotiated you should enable here some of 
                     23: encryption protocols.</p>
                     24: <p><b>Note:</b> In PPP, encryption should be handled by the ECP rather than CCP.  
                     25: However, Microsoft combined both compression and encryption 
                     26: into their ``compression'' algorithm (MPPC), which is confusing.</p>

                     31: <p>Sets the encryption key.</p>

                     34: <dt><b><code>set ecp deny <em>option ...</em> </code></b><dd>
                     35: <dt><b><code>set ecp enable <em>option ...</em> </code></b><dd>

                     38: <dt><b><code>set ecp no <em>option ...</em> </code></b><dd>
                     39: <p>These commands configure various ECP options. Each direction of
                     40: traffic (transmit and receive) is independent from the other.
                     41: All options default to <code><b>disable</b></code> and <code><b>deny</b></code>.</p>
                     42: <p>The <code><b>enable</b></code> and <code><b>disable</b></code> commands determine
                     43: whether we desire the corresponding option on received data.
                     44: The <code><b>accept</b></code> and <code><b>deny</b></code> commands determine
                     45: whether we will allow the peer to request the corresponding option
                     46: (which we must enable on our transmitted data).</p>
                     47: 
                     48: <p>The <b><code>yes</code></b> command is the same as
                     49: <code><b>enable</b></code> and <code><b>accept</b></code>.
                     50: The <b><code>no</code></b> command is the same as
                     51: <code><b>disable</b></code> and <code><b>deny</b></code>.</p>

                     68: <p><b>Note:</b> DESE protocol is deprecated. Because of data padding 
                     69: to the next 8 octets boundary, required by block nature of DES encryption, 
                     70: dese-old option can have interoperability issues with other protocols 
                     71: which work over it. As example, it is incompatible with Predictor-1 and 
                     72: Deflate compressions.</p>
