getByte

Gets one byte of data from the receive buffer and returns true or false depending on success or failure.

Not available at design time. Read only at runtime.

Only available with Comm32 - Not available with MSComm32

	Syntax	result = object.getByte(value)

	object	Name of the communications control.
	result	Boolean return value. true or false. Will be false if a byte could not be read from the receive buffer (ie if the buffer was empty)

	Example.
		Dim b as Byte If Comm1.getByte( b ) = True Then '// b contains the byte that was read Else '// No data was read - buffer was empty End If '// This example will attempt to read one byte from the receive buffer. This function retreives the byte as a numeric byte value. Not as a string/character. Use this function to read/receive byte values in the range 0 to 255 You do NOT need to change the OutputMode property. The getByte function ALWAYS reads a numeric byte value.

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.
