kick a drawer from asp.net

[Guest]

do you know how open/kick a cash drawer of POS system from ASP.NET page using
C# ? I have a webpage (asp.net/c#) doing POS functions (Point of sales). Once
users click a invoice button the attached drawer (to PC) should kick open but
I can't make it work. A drawer is attached to PC by a serial port.

To interact with a serial port you'll need a thick client of some kind, such
as an ActiveX control or a .NET component running on the client.

You'll need code on the POS computer (an ActiveX control, for example)
to fiddle with the serial ports. There are quite a few available, I
imagine you could find some for free (or the source code).

your page with the <object> tag and invoke commands on it with
JavaScript.
