NullDiscard

Indicates whether the com port will discard received Null characters

Available at design time and runtime.

MSComm32 and Comm32 have identical behavior

Syntax	object.NullDiscard = value

object	Name of the communications control.
value	A Boolean expression (Default is False)

Examples
	object.NullDiscard = True	'// Set the value

	If object.NullDiscard = True then MsgBox("NullDiscard is enabled") Else MsgBox("NullDiscard is disabled") End If	'// retrieve the current setting

Remarks:

If enabled then Null characters received by the hardware are simply ignored ie not entered into the receive buffer.

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.
