## Description
Pure framing protocol -- carries an arbitrary encapsulated packet (typically IP) with no application-level commands or integrity check of its own.

## Command Catalog & Message Signatures

### Category: GENERAL

#### `EncapsulatedPacket` (Command ID: `0x00`) - The opaque packet being carried (e.g. an IP datagram); SLIP does not interpret it.
