687 In practice, generally you don't need to specify any parameters,
688 except when you want to create a new frame on another terminal.
689 In that case, the `tty' parameter specifies the device file to open,
690 and the `tty-type' parameter specifies the terminal type. Example:
692 (make-terminal-frame '((tty . "/dev/pts/5") (tty-type . "xterm")))
694 Note that changing the size of one terminal frame automatically
695 affects all frames on the same terminal device. */)
