Serial driver supporting 16950 UART

NTDEV
1

Hi,

I have recently started working on a serial driver which has to support the
UARTs from 16550 to 16950 (i.e. 16550, 16650, 16750 and 16950).
I see that the sample code in (Windows XP) DDK supports only 16550 UART.
Does this mean that Microsoft supports only 16550 compatible serial ports,
and not greater than this?
Is there any way of getting the sample serial driver supporting 16950 UART?

Surprisingly I couldn’t find the UART 16550 standard document after
extensive search. Can somebody please tell me where can I get all these
standards (16550 to 16950)?
Thanks,

Regards,
Abhijit

I don’t think you will find a sample specific for 16650 and higher. You may look at http://ser8uart-driver.sourceforge.net/ ,
although it should not be a starting point for you driver.
UART specifications can be found at :
