Hyperterminal can handle the chars as fast as they come - at least up to 115K baud.
Debug is really a lot better than I thought. Unfortunately, I don't have a 12F running at 8Mhz. All I have is an 18F8723 running at 40Mhz.Name: DEBUG.jpg Views: 658 Size: 563.9 KB

I sent out $FF in a loop. Note that there is virtually no extra space between ANY of the bits. So DEBUG is very fast. But remember that DEBUG is a blocking command. If all you have to do is pull bytes out of an array and send them, you will see the same results I do, but if you have to calculate or use some logic between sending bytes, that will add a bit of time.
