Try removing the battery for 30 minutes.  This will clear the battery RAM 
which, among other things, contains serial port settings.  You'll need to 
reset your clock and other control panel settings, however.  A public 
program called PRAM  came out ages ago which allowed selective clearing of 
battery RAM.  You may find a copy still floating around.
