Data structures to simulate the behavior of a terminal I/O device.

Author

Olivier Hureau, Hugo Feydel , Julien ALaimo Data structures to simulate the behavior of a terminal I/O device. A terminal has two parts – a keyboard input, and a display output, each of which produces/accepts characters sequentially.

The console hardware device is asynchronous. When a character is written to the device, the routine returns immediately, and an interrupt handler is called later when the I/O completes. For reads, an interrupt handler is called when a character arrives.

The user of the device can specify the routines to be called when the read/write interrupts occur. There is a separate interrupt for read and write, and the device is "duplex" – a character can be outgoing and incoming at the same time.
