Serial Plug'n'Play?

I am looking for any pointers to Linux serial port Intel Plug
'n' Play support. I am referring not to Plug 'n' Play cards that have
a modem or serial port, but rather to the separate standard that
enables serial devices to provide certain identifying information via
the serial cable described in
ftp://ftp.microsoft.com/developr/drg/Plug-and-Play/Pnpspecs/PNPCOM.EXE
(of course, you have to run an .EXE file to unpack the standard and
then you get a Microsoft Word file--what a vendor netural standard!).
With serial PNP, it is possible to learn if a serial port is connected
to a serial PNP compatible modem, mouse or printer and also learn
some of the capabilities of the device.

The Intel PnP standard requires manipulation of certain
modem control lines within cerain time constaints. I am not sure
if it can be done entirely within userland under Linux or not, and
I would certainly like to avoid reintenving the wheel if somebody
else has thought about this or if there already exists software to
handle it.

Any pointers would be appreicated.
