I doubt it's necessary or even helpful to create @msg.

And populating it with the hex nibble pairs is particularly backwards. Populating it with the values of each bytes would make more sense if there's any reason to create @msg in the first place. 

my @msg = unpack('C*', $buffer);

...do something to @msg...

$buffer = pack('C*', @msg);
