If you attempt to open a port that does not exist or when it is already open a trapable runtime error will occur.

32bit development in VB6 using the Comm32 Communications OCX ?

Or are you looking for a proper .Net Component ?

Carry on using most of the common and well documented MSComm32 syntax but with a proper .net component allowing you to build x86, x64 and AnyCPU projects using Visual Studio 2005, 2008 and 2010.
