copied!<p><strong>pexpect</strong> has no <code>sendcontrol()</code> method. In your example you appear to be trying to send an empty line. To do that, use:</p> <pre><code> id.sendline('') </code></pre> <p>If you need to send real control characters then you can <code>send()</code> a string that contains the appropriate character value. For instance, to send a control-C you would:</p> <pre><code> id.send('\003') </code></pre> <p>or:</p> <pre><code> id.send(chr(3)) </code></pre> <p><em>Responses to comment #2:</em></p> <p>Sorry, I typo'ed the module name -- now fixed. More importantly, I was looking at old documentation on noah.org instead of the <a href="http://pexpect.sourceforge.net/pexpect.html">latest documentation at SourceForge</a>. The newer documentation does show a <code>sendcontrol()</code> method. It takes an argument that is either a letter (for instance, <code>sendcontrol('c')</code> sends a control-C) or one of a variety of punctuation characters representing the control characters that don't correspond to letters. But really <code>sendcontrol()</code> is just a convenient wrapper around the <code>send()</code> method, which is what <code>sendcontrol()</code> calls after after it has calculated the actual value that you want to send. You can read the source for yourself at <a href="http://pexpect.svn.sourceforge.net/viewvc/pexpect/trunk/pexpect/pexpect.py?revision=521&view=markup">line 973 of this file</a>.</p> <p>I don't understand why <code>id.sendline('')</code> does not work, especially given that it apparently works for sending the user name to the spawned <strong>ftp</strong> program. If you want to try using <code>sendcontrol()</code> instead then that would be either:</p> <pre><code> id.sendcontrol('j') </code></pre> <p>to send a Linefeed character (which is control-j, or decimal 10) or:</p> <pre><code> id.sendcontrol('m') </code></pre> <p>to send a Carriage Return (which is control-m, or decimal 13).</p> <p>If those don't work then please explain exactly what does happen, and how that differs from what you wanted or expected to happen.</p>
