	AH = 1Ah
	BX = network descriptor
	CX = number of bytes to transmit (0000h allowed)
	DX = send options (see #03464)
	DS:SI -> data to be written
Return: CF clear if successful
	    AX = number of bytes actually written
	    DX = ???
	CF set on error
	    AX = error code (see #03319 at INT 61"FTP(File Transfer Protocol)  The standard protocol for copying files from one machine to another on a TCP/IP (Internet) network.  Also the program of the same name with which a user may transfer files. Software")
