I gave that a try and just got a different unknown character in hyperterm. I added DEFINE OSCCAL_1K 1 and got an even different result. I read that the 12f675 internal osc may need calibrated. I have no idea if the factory cal has been messed with. I tried the link below from microchip, but it wont compile, with a bunch of errors. From what I read it seems to be a timing problem. Also tried powering with 3.3v instead of 5v and got yet a different result. I have an external crystal here that has 5.000 on it, so I assume that is 5mhz. Will this work for a test? Researching now on how to hook up an external chrystal.
