external clock / internal clock

[grounded]

thanks
I'm adding a 4 mhz crystal
I'm trying to do some PIC to PC comm. using DEBUG.
Melanie's Communications Example : PC to PIC bi-directional dialogue
and with the internal I was having the problem she talked about hoping the external will solve it

If you are using one with built in capacitors use HS.

thanks again
I used ext caps so I guess that would be XT
