Hi,
I have example code in my book (several variations), including a native .NET
class that P/Invokes the underlying Windows serial communications APIs. I
provide a free ActiveX control on my website called NETComm.ocx, designed to
make serial IO pretty easy. It wraps the functionality of MSComm32.ocx.
There are a number of serial classes available for download, to. One is on
http://msdn.microsoft.com/vbasic/downloads/samples/default.aspx.
Sax Software (
www.sax.net) sells a .NET component that I have used, and they
provide a free version, with no extra features, too.
