<pre><b>INT 61 - PC/TCP kernel v2.05+ - "get_option" - GET OPTIONS APPLIED TO NET DESCR</b>

	AH = 21h
	BX = network descriptor
	CX = length of buffer
	DS:DX -&gt; buffer for return values
	SI = 0004h (ignored by v2.2-)
	DI = option (see <a href=../../it/68/34.html>#03468</a>)
Return: CF clear if successful
	    DS:DX -&gt; value (usually 32 bits) returned by selected option
	CF set on error
	    AX = error code (see <a href=../../it/19/33.html>#03319</a> at INT 61"FTP Software")
Notes:	this function is not supported by Beame&ampWhiteside's BWPCTCP v3.0a shim
	v2.11 reportedly stores the actual 32-bit value of an option in DS:DX
	  rather than using a buffer in memory
