<P>


<P>
The <tt class=module>telnetlib</tt> module provides a <tt class=class>Telnet</tt> class that
implements the Telnet protocol.  See <span class=rfc><a name="rfcref-42506"
href="http://info.internet.isi.edu/in-notes/rfc/files/rfc854.txt">RFC 854</a></span> for details about the
protocol.

<P>
<dl><dt><b><a name="l2h-1782"><tt class=class>Telnet</tt></a></b> (<big>[</big><var>host</var><big>[</big><var>, port</var><big>]</big><big>]</big>)
<dd>
<tt class=class>Telnet</tt> represents a connection to a telnet server. The
instance is initially not connected; the <tt class=method>open()</tt> method must
be used to establish a connection.  Alternatively, the host name and
optional port number can be passed to the constructor, too.

<P>
Do not reopen an already connected instance.

<P>
This class has many <tt class=method>read_*()</tt> methods.  Note that some of them 
raise <tt class=exception>EOFError</tt> when the end of the connection is read,
because they can return an empty string for other reasons.  See the
individual descriptions below.
