UART Description

UART is a simple command line tool that lets you check that your COM ports are configured correctly, with the standard hex port address e.g. COM4: should be at 2e8, and with the standard IRQ, e.g. COM4 should be IRQ 3. It also tells you what type of UART chip you have, usually the old fashioned unbuffered 8250 or the newer fifo buffered 16450 that is needed for Windows and OS/2.
