A remote login to another system; 2. A pseudo-terminal (/dev/ttypnn or PTYnn:); 3. A protocol; 4. An abstract object that a program speaks to as if it were a physical device, but which another program supplies the translation or interpretation for; 5. An abstract specification for an ideal (or real) terminal (see also, "termcap"); a reference model. For example, a window manager might present the view of a specific virtual terminal, say a DEC VT-100, to each of the processes running under it, while actually displaying the output in various sized boxes on a physical ADM3 or an IBM PC. To say "a presentation layer protocol (ISO/OSI level 6)" is probably closest.
