Command 0x10 is ENTER_PROGMODE_ISP (the command code is always the 6th
octet sent to the STK500).  I think that's the first command where the
STK500 is actually going to talk ISP to the target (everything before
has been setting up the parameters in the STK itself).  So if that
fails, it means the target isn't responding at all.  Either one of the
connections is not OK, or ISP programming had been disabled somehow
(which on the ATmega163 could only happen through high-voltage
parallel programming as there is no JTAG), or the target's clock is
not operational (perhaps due to a wrong fuse setting).
