You missed a condition, namely that it is not possible to add a PCI or 
ISA serial card.

For electronic hobbies, there are advantages in having a more directly 
connected serial card, e.g.

- you will need it for accurate time synchronisation to a hardware clock;
- you will need it for certain sorts of, timing critical, simple 
hardware interfaces, such as PIC programmers.
