-
         * **signal**(< _string_ >signalName) - _boolean_ - Sends a POSIX signal to the current process on the server. Valid signal names are: 'ABRT', 'ALRM', 'FPE', 'HUP', 'ILL', 'INT', 'KILL', 'PIPE', 'QUIT', 'SEGV', 'TERM', 'USR1', and 'USR2'. Some server implementations may ignore this request if they do not support signals. Note: If you are trying to send SIGINT and you find `signal()` doesn't work, try writing `'\x03'` to the Channel stream instead. Returns `false` if you should wait for the `continue` event before sending any more traffic.
 
         * **setWindow**(< _integer_ >rows, < _integer_ >cols, < _integer_ >height, < _integer_ >width) - _boolean_ - Lets the server know that the local terminal window has been resized. The meaning of these arguments are described in the 'Pseudo-TTY settings' section. Returns `false` if you should wait for the `continue` event before sending any more traffic.
