Log Message:
-----------

Provides footwork for "ie. dsctl firmware BCD996T_V1_03_11.scn"

$ hexedit BC_VUP.exe (to get a scenario of what I'm doing)

There are four to six special commands (ie. *MDL, *PRG, *ULE, ...) used for 
uploading the firmware.  I've commented the code in commands.c (load_firmware
function).  Just need to write the minor functions to make it tidy.

*Note: Some commands I don't know what they do, so I'm dragging my feet in
hopes of figuring out what these commands specifically do so I can write
comprehendable code.
