Is there any possibility of plain ordinary VT100 or VT220 emulation with SimH? I have the impression that telnet can do this in some manner, but I have no idea exactly how. IN ADDITION, the RT-11 monitors I use have multi-terminal support, usually for DLV11-J serial ports, but sometimes for DZV11 and / or DHV11 serial ports. Can SimH handle that emulation as well? And can there also be VT100 emulation for those multi-terminal serial ports as well? It may be possible to have a separate PC emulating a VT100 operating via an actual physical hardware serial port. But that would seem to be a huge waste of resources when it is possible for a single PC running SimH to support all of the serial ports with VT100 emulation in some manner although I agree that is not how SimH functions at present. Of course, for minimal testing of certain RT-11 features, it would be possible to execute under SimH using just an simple output device similar to a consol printer. However, I frequently use KED to edit my files and that obviously requires VT100 emulation. TECO is possible, but is so clumsy that other solutions which support VT100 emulation with all types of serial ports are preferred. Jerome Fine
