def check_channel_pty_request(<EOL>self, channel, term, width, height, pixelwidth, pixelheight, modes<EOL>):
return False<EOL>
Determine if a pseudo-terminal of the given dimensions (usually
requested for shell access) can be provided on the given channel.

The default implementation always returns ``False``.

:param .Channel channel: the `.Channel` the pty request arrived on.
:param str term: type of terminal requested (for example, ``"vt100"``).
:param int width: width of screen in characters.
:param int height: height of screen in characters.
:param int pixelwidth:
    width of screen in pixels, if known (may be ``0`` if unknown).
:param int pixelheight:
    height of screen in pixels, if known (may be ``0`` if unknown).
:return:
    ``True`` if the pseudo-terminal has been allocated; ``False``
    otherwise.
