Protocol Field
The Protocol field is consistent with the ISO 3309 (HDLC) extension
mechanism for Address fields. All Protocols are assigned such that
the least significant bit of the most significant octet equals "0",
and the least significant bit of the least significant octet equals
"1".
Presently the only defined protocol type is 0x99 (Addressed Serial
Data).
i.e. All frames start with 0x7E, 0x99
Information Field

+----------------+------------------+
| Remote Address | Application Data |
| 32 bits | *

device in network byte order.
