String Formatting Extensions
Any character can be inserted into the send, expect, and expect_case strings using the backslash (\)
character followed by an octal number of no more than three characters. For example, to send a
newline character (octal: 12), insert a \12 in the send string. The sequence of octal numbers following
the backslash character cannot exceed 377 (255 decimal). Some control characters can also be
represented as follows:
Name Decimal Value Representation
BEL 7 \a
BS 8 \b
call Executes another chat script.
sleep Causes a pause in the script for <sleep length> in
seconds.
send Sends a string. The string must be enclosed in double
quotes. Multiple strings can be entered on one line or
on multiple lines.
expect
expect_case
Sends control to another script upon reception of a
string; the first match is used. When <string> is
received, <script name> is called; the default is
continue. The expect field is not case-sensitive. The
expect_case field is for use with case-sensitive
matches. You can block together multiple expect
statements:
expect <string 1>, <script 1>
expect <string 2>, <script 1>
expect <string 3>, <script 3>
timeout Specifies the total amount of time to wait (in seconds)
for strings defined in a block of expect statements.
The timeout statement terminates a block of expect
statements. The <script name> is the chat script name
to execute upon timeout; the default is error.
end_script Marks the end of a chat script.
