Problem is, if you overrun by even one byte this will erase the next page. Definitely not more than 8192 bytes?

The file in question is ~ele_up.~tm, and as far as I know, it should never exceed 8192 bytes. It should always be exactly that size. Anyone who can show me otherwise, should do so ASAP.

Now I will concede that there could be an error in "upload.exe". But that is primarily someone else's *COUGH*your*COUGH* code. I only added the reboot code and a small bit of Windows serial-port initialization.
