* Uniden Digital backend should work for:
* BCD996T as well as the BCD396T. Some protocols available for the
* BCD996T may not be available for the BCD396T or modified to work.
*
* Protocol information can be found here:
* http://www.uniden.com/files/BCD396T_Protocol.pdf
* http://www.uniden.com/files/BCD996T_Protocol.pdf
*
* There are undocumented commands such as firmware_dump and
* firmware_load. These commands are defined within DSctl code.
*
* There are two methods of retrieving the next memory location
* (aka frequency bank). Use either the "Get Next Location" or
* use the address returned from one of the commands. If you decide
* the latter method, the order is slightly confusing but, I have it
* well documented within DSctl. The latter method is also as much
* as 30% faster then using the Uniden software or "Get Next
* Location" command.
