It looks like the code is assuming there's more than one uart while
the 18f252 only has one. A few define statements added to the code
could fix that. Also, I don't have a datasheet in front of me right
now, but I see that the 18f252 has 256 bytes of eeprom. Since the
address would fit in 8 bits, it would not need a high byte for the
eeprom address. So, eeaddrh may not exist.
     Their bootloader is interesting. The checking of eeprom to decide
whether to bootload or run the ap is a bit different. I changed that
to polling a switch. I also got rid of all the autobaud stuff. I know
how fast I want the port to go.
     I've got it working on an 18f6720.
