- UART tests your COM port configuration.
- UART 1.2 tells COMx: hex i/o port, type of UART, and IRQ.
- usage: UART Com4:
- returns:
- COM4: is at hex port address: 02E8.
- AT style 16450 unbuffered UART.
- Port correctly configured to IRQ 3.
-
- UART will tell if the hex port address
- configured is correct and what it
- should be.

- Long description:
- UART 1.2 tells COMx: hex i/o port, type of UART, and IRQ.
- usage: UART Com4:
- returns:
- COM4: is at hex port address: 02E8.
- AT style 16450 unbuffered UART.
- Port correctly configured to IRQ 3.
-
- Works on Com1: through Com4: It can discriminate XT style
- 8250, AT unbuffered 16450, AT buffered 16550AF, and PS/2
- style Type 3 DMA. It displays a message and sets the
- errorlevel.
-
- It can be fooled by OS/2 which virtualizes all chips to
- look like the old 8250. DESQview can prevent UART from
- accessing COM ports if you don't give permission in the
- PIF. Don't use UART on com ports that are actively being
- used by a mouse or modem. UART works by temporarily
- reprogramming the port and sending it a NUL character.
-
- UART will tell if the hex port address configured is
- correct and what it should be.

- IRQ is correctly configured, and provides more detailed
- information on use and troubleshooting.
