ikegami - I found out I need to be able to handle one or two bytes worth of data adding nine or eight spaces: e.g., 00 20 20 20 20 20 20 20 20 20 or 00 00 20 20 20 20 20 20 20 20 Is there something smaller than an unsigned short (16bit)? I'm trying to figure out the correct pack template to use for the above examples.
