+

Once a logical channel and a physical channel, if appropriate, have +been created and initialised, the driver is ready to handle requests.

On +the kernel-side, requests can be handled by one or more kernel-side threads, +allowing for rich and complex behaviour. Alternatively, if appropriate, a +request can be handled by code running in the context of the client user-side +thread, but running in supervisor mode.

There are two kinds of request, +synchronous and asynchronous.
