You could create three config files: a serial-port oriented file, a
regular console oriented one and a selector where you'd select if
you're using a serial port or regular console.

A simple extension of HPA's DISPLAY comment is use the above idea
(without a menu at first) and display something like "press <enter> to
continue" to the regular console and "type s<enter> to continue" on
the serial port.
