In my first quick reading of the user manual I had thought that
referred to the standard uuencode checksum but on re-reading it
doesn't appear to.  My suggestion would be to use the read memory
command to reverse engineer it.  I suspect it's just a simple byte
checksum (or possibly it's compliment), i.e. checksum = byte1 + byte2
+ byte3 + ....

One other thing I noticed in  my testing.  The version command is
appears to be documented as returning <major>.<minor>  It actually
returns the two numbers on separate lines.

I think it's just a matter of clarity not an actual documentation bug.

The Philips utility is nice but I'd sure like a command line utility
to replace it (I just have other things to do first).
