INT 61 - PCIBM PC/TCP(Transmission Control Protocol) A higher level (session layer) of the TCP/IP protocol suite.  See also IP, TCP/IP. kernel v2.05+ - "net_listen" - LISTEN FOR INCOMING CONNECTIONS
	AH = 23h
	BX = network descriptor or FFFFh to allocate descriptor
	DX = type of service
	DS:SI -> "addr" structure (see #03462)
Return: CF clear if successful
	    AX = network descriptor
	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")
Notes:	type of service and "addr" structure are as for AH=13h
	any of the address structure can be zero; normally local socket number
	  is filled in prior to call
