Installing Serial Devices that Use a 16550 UART-Compatible Interface
To install a Plug and Play device that uses Serial as a lower-level device filter driver, do the following:
Specify Serial as a lower-level device filter driver in the device's INF file -- see Installing a Filter Driver.
Set the SerialSkipExternalNaming entry value for the device to a nonzero value -- see Registry Settings for a Plug and Play Serial Device.
