That's what I've ended up with actually - at least for going from hex to
binary. Hexdump handles the other way around quite happily!

I dislike writing C, but I dislike writing Perl even more :-)

I couldn't figure out a good way of doing this with awk - I'm capable of
writing some awk to format output, but not to actual interpret data, do
calculations with it, and spit it out in a different format...

Anyway, problem solved. It's a stop-gap measure as the comms software I
have under Linux doesn't like capturing binary data from the EPROM
programmer, so I have to dump stuff in hex format (but would rather have
stored on the PC in binary format). I'll sort out a better method
sometime ('cat /dev/serialport > file' would be nice!)

cheers
