INT 5B - AT&TAmerican Telephone and Telegraph Starlan Extended NetBIOSOne of a number of low-level device-independent network interfaces; the other major interfaces are Novell's IPX and the Internet's IP (Internet Protocol, the lower-level portion of TCP/IP). (variable length names)
	ES:BX -> Network Control BlockA Network Control Block used to pass requests to NetBIOS and receive status information from the NetBIOS handler. (see #03245)
Return: AL = status (see #03248)
