*																									 *
* History :																						 *
*																									 *
*				01/10/93		:	Beta release 1.00											 *
*				23/12/93		:	All receives now LocalAlloc()                    *
* 1.00.00	29/12/93		:	NetVersion() added										 *
*									Implementation specific error codes added			 *
*									with bit 7 of NCB return code set					 *
* 1.01.00	07/01/98		:  Allows adaptor to be specified in INI file		 *
* 2.00.00	12/08/98		:  Converted to use Netbios() call for 32 bit dll	 *
* 3.00.00   13/08/01    :  Added NetSetAdaptor() && NetSetAdaptor()         *
* 4.2.0.0   20/02/09		enables 10 times better message reception
* 4.2.0.1   23/02/09		on site (bit of a tidyup)
* 4.2.0.2	23/02/09        checks in DG post routine for call cancelled
* 4.2.0.3	23/02/09		puts thread protection around the queue calls
* 4.2.0.4	16/07/09		show version info tab in file properties
