Introduction

This specification defines the serial protocol used between OpenKitchen Equipment (OKE) and the ConnectWare Module (CWM). The serial protocol allows OpenKitchen functionality to run on small, memory constrained microcontrollers.

The serial protocol stack is comprised of several layers. The first layer is the physical interface that provides the signaling medium. The second layer is the data link layer that defines how data frames are transported on the physical interface. The third layer is the network layer that provides message fragmentation, reassembly, and retries on top of the data link layer.

OpenKitchen Messages (OKMs) are transported between OKE and its CWM using the serial protocol described by this document.
