???:	HOW TO CONNECT TP4 AND TCP/IP NETS    :???
	----------------------------------

	I  need  make  our  Unix-V.2-like  680x0-system  network using
	OSI/TP4 (but not TCP/IP) to support such nice things as:  NFS,
	RFS, TELNET, Rlogin,  Remote Proc  Call so  they can cooperate
	with  another  680x0-systems  run  under  V.3(V.4)  supporting
	TCP/IP (but not TP4).

	There is another  system-family (a  386-based) that fortunately
	supports both TP4 and TCP.

	An idea I have, is to add a gateway system  converting TP4 <->
	TCP, and then write a "black  box" leyer  between NFS, Telnet,
	...,  and TP4:


	+-----+   +--------+                                   +--------------+
	! NFS !...! Rlogin !                                   ! NFS...Rlogin !
	+-----+---+--------+       +-------------------+       !              !
	! black box appl   !       ! Gateway +         !       !              !
	! conv TP4/TCP     !       ! conv    TCP/TP4   !       !              !
	+------------------+       +----------+--------+       +--------------+
	! ISO 8073 Cl4     !       ! 8073 Cl4 ! TCP    !       ! TCP          !
	+------------------+       +----------+--------+       +--------------+
	! 'Ethernet'       !-------! Eth.     ! Eth.   !-------! Eth.         !
	+------------------+	   +----------+--------+       +--------------+

	system in						system in
	OSI-network		     Gateway (386)		TCP/IP-network


	Questions:

1.	Is it possible to translate TCP/IP <--> ISO8073 Cl4?

2.	Is it easy to write a "black-box" and Gateway session layer programs?
	Or maybe it exists somewhere????

3.	Will NFS, Rlogin,... be satisfied by such an arrangement?
