Advanced IPC under specification phase; in the meanwhile we have developed and tested the serial driver (running as a daemon process as the keyboard one). Services can register dynamically with the kernel. A screenshot shows the daemon printing a message received from the serial port (using bochs and the serial port emulation). We have conducted a private test sending messages via the serial port from/to a sinclair spectrum old computer.
List of available daemons: keyboard, serial, simple readonly ramdisk, ocaml virtual machine.
