Strange SerOut Problem

[masosi]

No, but it makes sense that without the resistor, you probably smoked all of your ports.

I'm using the same COM port to program the PIC using JDM2 serial programmer and WinPic - there are no errors there, so the COM port should be fine!?

But...back to the timing thing. The LED blinks, ok... Back to basics...
Do you have an LCD? Make a counter, one second, power up the PIC, start your stopwatch. Wait for 100 seconds. If your watch and the PIC/LCD match up after 100 seconds, you can be reasonably sure you're within 1-2% of the 4Mhz clock speed. The longer you go, the more accurately you can count it up.

I just did a Pause command of 2mins, timing it showed up as 2mins 2secs. Is this too far out?
