control type for a newbie

[Mike D]

I want to write an app that can connect to a client side comm port. This
port will be connected to a balance, I will need to send commands to and
receive data from the balance.

I would like this portion of the app to be ran in IE because this is part of
a larger app that will be all asp.net pages. I can do this in ActiveX but
would like to do it in dotnet. Do I need to use a Windows Form Control?? If
so how do I deploy it?

Any links or advice greatly appreciated.

Mike
