18: <H2><A NAME="58"></A>6.4.1. Special variables</H2>
19: <p>These variables have special meaning in chat scripts:</p>
20: <p>
21: <dl>
22:
23: <dt><b><code>$Login</code></b><dd><p>Authorization login name as set by <code>set auth authname</code>.</p>
24:
25: <dt><b><code>$Password</code></b><dd><p>The password corresponding to <code>$Login</code>.</p>
26:
27: <dt><b><code>$modemDevice</code></b><dd><p>The serial port device in use as set by the
28: <code>set modem device</code> command, e.g., <code>/dev/cuau0</code>.
29: Changing this string does not change the port being used.</p>
30:
31: <dt><b><code>$Baudrate</code></b><dd><p>Always equals the current baudrate (e.g., ``57600''). This
32: is a read/write variable; setting it changes the baudrate.
33: Attempting to set an invalid baudrate causes the script to fail.</p>
34:
35: <dt><b><code>$matchedString</code></b><dd><p>When a <code>match</code> event occurs this string contains
36: the input string that matched the pattern.</p>
37:
38: <dt><b><code>$matchedString0 </code></b><dd>
39: <dt><b><code>$matchedString1 </code></b><dd>
40: <dt><b><code>$matchedString2 </code></b><dd>
41: <dt><b><code>... </code></b><dd>
42: <p>When a <code>regex</code> event occurs or the <code>if match</code> or
43: <code>if !match</code> commands are executed, and the regular
44: expression pattern contains parenthesized subexpressions, these
45: strings will be equal to the substrings matching each subexpression.
46: <code>$matchedString0</code> is equal to the entire string, while
47: <code>$matchedString1</code> equals the first subexpression match,
48: <code>$matchedString2</code> the second, etc.</p>
49:
50: <dt><b><code>$IdleResult</code></b><dd><p>This variable is used to return the result of an <b>idle
51: script</b>; If the value is <code>answer</code>, mpd assumes an
52: incoming call has been answered. If the value is <code>ringback</code>,
53: mpd will initiate an outgoing connection. See the chapter on
54: <A HREF="mpd43.html#modem">Modem type commands</A> for more information.</p>
55:
56: <dt><b><code>$$</code></b><dd><p>Always expands to a single dollar sign.</p>
