Output of file : UART.USE contained in archive : UART12.ZIP
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.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
