INT 61 - Banyan VINES - SEND MESSAGE ON A SOCKET                                
	AX = 000Fh subfn 0002h
	CX:BX -> request block (see #03447)
	DX = application's data segment (should be = CX)
	ES = DS
Return: AX = status
	    0000h successful
	    00A5h resource not available
Desc:	send data to a socket identified by its socket handle


Format of request block:
Offset	Size	Description	(Table 03447)
 00h	WORD	0002h
 02h	WORD	magic number (FEFEh)
 04h	WORD	buffer for return code (set to 0 before calling)
 06h	WORD	reserved (will be set to client DS)
 08h	WORD	reserved (obviously not used; set to 0 before calling)
 0Ah	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	far pointer to parameter block (see #03448)
 0Eh	WORD	process handle (see AX=000Fh/SF=0008h)


Format of parameter block:
Offset	Size	Description	(Table 03448)
 00h	WORD	buffer for estimated communication cost in 220 msec ticks
 02h	WORD	buffer for return code (set to 0 before calling)
 04h	WORD	socket handle
 06h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	far pointer to IPC(Inter-Process Communication) Any one of numerous methods for allowing two or more separate processes to exchange data./SPP message buffer
 0Ah	WORD	length of IPC(Inter-Process Communication) Any one of numerous methods for allowing two or more separate processes to exchange data./SPP message buffer
 0Ch	WORD	option flags
		bit 0: asynchronous communication
		bit 1: reliable message
		bit 3: end of message
		bit 4: vectored I/O
 0Eh 16	BYTEs	socket address (IPC(Inter-Process Communication) Any one of numerous methods for allowing two or more separate processes to exchange data. port of source)
 1Eh	WORD	not used (set to 0 before calling)
 20h	WORD	SPP connection id (0 for IPC(Inter-Process Communication) Any one of numerous methods for allowing two or more separate processes to exchange data. messages)
 22h	WORD	request type (1 = data, 2 = connect SPP, 3 = disconnect SPP)
