  The Wacom tablet is very like a mouse -- it uses its IRQ *all the
time*.  This is what's conflicting with COM3.

  How to fix it?  Well, there are three approaches:

1.  Move COM3 to some non-standard IRQ.  You might not have one
available.

2.  Move COM3/IRQ4 to COM4/IRQ3.  You won't be able to use the card
reader at the same time as the modem, but I expect you can live with
that.  A few kinds of video cards conflict with COM4, but you might
not have one of those.

3.  [My favourite...]  Make the internal modem COM1/IRQ4 and move the
Wacom tablet to COM2/IRQ3.  The card reader should then work as
COM3/IRQ4.  Again, you won't be able to use it and the modem at the
same time, but this shouldn't get you into any other difficulties.
