0x78 - Network Information (request) - 6 bytes
Message 0x78 is a block used to request Network information to be compiled by NCT-2100D
and provided to the user. It uses a sub-ID located in W2 to determine requested information.
(The standard block request process using Message 0x20 does not support this Command.)
The message length determines if the block is a request or a response. A request message is
always 6 bytes. Note that the response time may be a few seconds while the information is
gathered.
Network List (0x01) - Request for network list.
