EEPROM programmer

I've worked on the EEPROM programmer some more -- mostly interface stuff for the PC-side of things. It took me quite a while to get my mind around the whole checksum-business for the HEX-format -- apparently you have to checksum all the bytes on the line, and not just the data bytes.
I'm now working on sequentially writing the contents of the buffer to the EEPROM. However, the communication between PC and PIC can reach a deadlock. Sadly, this is not at always the same point, so it's a rather nebulous affair to debug.
