The Maple bus normally runs at 2 Mbps.  It is theoretically possible
to select other speeds (up to 8 Mbps), but I havent checked if it
really works in practice.  It's not supported by current peripherals.

Each port runs in half duplex (peripherals may only talk as a direct
response to commands sent by the host, within a certain timespan).
Commands and responses are packets with an MTU of 1KBytes, including
header (4 bytes).
