Reading from a Serial/COM port in asp.net?

[Seboko]

Is it possible have an ASP.net web application to read from a Serial/COM port? I am writing an ASP.net(with C#) web app which will display some information to a few client computers and I need it to have coupon readers attached to the client machines and th app needs to read from the coupon readers.

Is this possible? May be I need an ActiveX control - but if so, how do I use it?

I'm told it can be done using System.IO.Ports
