LPT detection on Win XP using C#

[luco]

Hello!
In my application I need to detect how many parallel ports there are
in a machine I'm using and what their state is. Is it possible in C#?
Any ideas how to do it?

thanks in advance,
Lukasz

Well System.IO.Ports.SerialPort reads from
@"HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM", so you can probably
read the parallel port information from the registry in a similar way.
