Fix Bug in Router Login Password CLI Menu

While entering the Router Login Password string on the CLI menu dialog, if you happen to (accidentally) press any of following special keys:

<UP_Arrow>, <DOWN_Arrow>, <LEFT_Arrow>, <RIGHT_Arrow>, <HOME>, <END> <PAGE_UP>, <PAGE_DOWN>

The password input dialog gets canceled and exits, acting as if the <ESC> key had been pressed.
