Monitoring your program with a serial communication will, at least, cost you 3 ports (2 for crystal + 1 for serial comm.).

This can be especially critical when you are using small PICs.

Thanks for pointing to your routine - can be really usefull.
Hi flotulopex,
There is another way, andthat is to use an dedicated External Oscillator Chip.
As I understand it you lose 1 pin.
