<pre><b>INT 7C - SK-UPPS Data Link Interface API - REQUEST BUFFER</b>

	AX = 0004h
	DX = protocol ID (see AX=0007h,<a href=../../it/49/38.html>#03849</a>)
Return: AX = completion code (see also <a href=../../it/46/38.html>#03846</a>)
	    0000h successful
		ES:BX -&gt; Memory Buffer (Mbuf) (see <a href=../../it/47/38.html>#03847</a>)
Note:	if the DLI has no free Mbufs, it will set an internal flag for the
	  protocol and later call the protocol's Event Upcall with
	  EV_BUFFER_AVAILABLE (see <a href=../../it/53/38.html>#03853</a>,<a href=../../it/54/38.html>#03854</a>) as soon as an Mbuf becomes
	  available.  There will only be one "buffer available" Upcall, even
	  if this function has been called several times before.
