TTY Driver

The TTY driver is built on top of the UART driver (or other TTY appropriate hardware). The driver is responsible for sending and receiving character input between a user program level, such as the XINU Shell, and a char-oriented hardware driver. Line buffering and cooking are the two primary responsibilities for the new TTY driver.
