Chat In and Chat Out Scripts
The properties file and command line options use short scripts to control the logging in and out of the target system.
These scripts form a single line in the expect-send format (for chat in
scripts) or send-expect format (for chat out scripts). The format is:
ChatinString : <expect> <send> <expect> <send> ...
ChatoutString : <send> <expect> <send> <expect>
Note: The elements in the chat strings are separated by white space. In order
to send or expect a sequence that includes white space, surround the sequence
with single quotes.
A typical chat in script might be:
".*login.*:.*anu\r\n.*assword.*:.*anu\r\n"
The expect text can use any regular expression, while the send text can send any characters (including control characters) using the standard UNIX/C escape sequences described in Escape Codes.
