To me, the bigger surprise is not using one of the standard HEX =20
formats for the data transfer.  Those carefully avoid putting binary =20
data in the data stream, and have the checksum per line that ought to =20
detect most errors...  (Though I wonder just how many of the =20
bootloaders I use actually check those checksums.)

In some sense, this is a sort of "standard mistake" for Desktop PC =20
programmers faced with their first example of "real" multi-vendor data =20
communications (not coddled over some consumer-grade shrink-wrapped =20
set of hardware and drivers (like USB))  But I would have expected =20
better based on the author's reported background...

I do have to admit that a lot of the software development practices I =20
used to think were "normal" early in my career, now seem extremely =20
primitive and naive...
