RFC: Serial port messages

[Fernando Nasser <fnasser at cygnus dot com>]

The following patch prevents that we give the user misleading
information.

I rather do this than conditionalize the code for the OS.  By being
presented with a list the user will become aware that he must know the
right way to specify a port in his/her system.
