Sets or Retrieves the number of bytes in the Output (Transmit) buffers.

Not available at design time.

Syntax	value = object.OutbufferCount

object	Name of the communications control.
value	A numerical expression indicating the number of bytes in the transmit buffer.

Examples
	Text1.Text = object.OutbufferCount	'// Retrieves the number of bytes in '// the transmit buffer.

	object.OutbufferCount = 0	'// Delete all data from the transmit '// buffer

Remarks:

This property is primarily a "Read" property allowing you to retrieve the number of bytes in the transmit buffer. The only value that can be written to this property is 0 (zero) which can be used to delete all data from the 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.
