You can use the UNIX utility 'dd' to read a section of a binary file
given the start point and length.
For example skip 4 bytes (start at 5th) and output the next 3 bytes...
echo '1234567890' | dd bs=1 skip=4 count=3 2>/dev/null; echo ''
567
The 2>/dev/null junks the dd report it outputs to STDERR
the final 'echo' is to add a extra return character to the end of the 3
bytes 'dd' extracts.
