- Which is fine, but you need to change a jumper on the serial port to tell it that it
- is IRQ 5 now - changing the sources won't do anything at all if you don't change the
- hardware. If your serial board won't let you change the IRQ to 5, you're outa luck.
- Once it's on IRQ 5 it should work fine
- (and if you're using the AUTO_IRQ #define, you shouldn't have to even change that line
- in serial.c any more)
-
- (Yep, It works for me now, TyTso (the AUTO_IRQ) !)

- Happy serialling !
