Both VT and RFA can be used to access remote terminals. In
either case, a FILE command or FOPEN
call must indicate that the file in question is actually a remote
terminal. If you specify the VTERM
option in the FILE command or the device
parameter of the FOPEN call, the
terminal will be accessed through Reverse VT rather than RFA. In
both cases the remote terminal functions as a non-session I/O device.
If the remote terminal is accessed through Reverse VT, you do not
establish a session on the system to which the terminal is attached.
