To peek at what's been received, use the command:
peek will display the characters received from the remote system while you are in command mode or while a script is executing. peek will continue to display characters as they are received until no characters are received for the specified number of seconds.
peek will empty Autolog's
holding buffer, so it shouldn't be used if part
of what will be displayed may be some prompt or response you will look
for in a later if or until
command.
