The buffer memory is electrically connected to the CPU and configured for storing messages sent to or from the CPU. The co-processor is electrically connected for providing an interface between the network and the host processor, and is configured for responding to tokens and for delivering messages from the network to the buffer memory for retrieval by the CPU, and for delivering to the network messages stored in the buffer memory by the CPU.
