You can create multiple frames on a single text-only terminal, but
only one of them (the selected terminal frame) is actually displayed.

In practice, generally you don't need to specify any parameters,
except when you want to create a new frame on another terminal.
In that case, the `tty' parameter specifies the device file to open,
and the `tty-type' parameter specifies the terminal type.  Example:

   (make-terminal-frame '((tty . "/dev/pts/5") (tty-type . "xterm")))

683 684

affects all frames on the same terminal device.  */)
