Get System Info
When receiving the Get System Info command, the LRI64 send back its information data in
the Response.The Option_Flag is not supported and must be set to 0. The Get System Info
can be issued in both addressed and non addressed modes.
The Request Frame
If there is no error, at the LRI64, the Response Frame
Otherwise, if there is an error, the Response Frame
