INT 21 P - Phar Lap 386/DOS-Extender - GET REAL-MODE LINK INFORMATION           
	AX = 250Dh
Return: CF clear
	EAX = CS:IP(Internet Protocol) The lower level (transport layer) of the TCP/IP protocol suite.	See also TCP, TCP/IP. of real-mode callback procedure (see #01358) that will
		  call through from real mode to a protected-mode routine
	EBX = 32-bit real-mode address of intermode call data buffer
	ECX = size in bytes of intermode call data buffer
	ES:EDX = protected-mode address of intermode call data buffer
Notes:	this function is also supported by FlashTek X-32VM
	X-32VM guarantees the intermode buffer to be at least 4 KB

	STACK:	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	offset to protected-mode code
		WORD	placeholder for protected-mode CS
		DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	pointer to selector structure (see #01359)
			or 0000h:0000h for defaults
		var	parameters for protected-mode procedure
Return: via FAR return
