unpack takes a binary string and turns it into a list. the H* is the
template used to pack/unpack...H* i think is a template to do a
Hexdecimal pack/unpack. I would first try
tobinary(tostring(packed_var)) and see where that leads and work form
there...I do a good bit of perl programing but never use pack/unpack
just remember it from one of my Perl Trainings :)
