There are many reasons for supporting "1822" (the host-to-imp protocol) in SimH in a generic way:
To speak to a simulated pre-TCP-era (aka NCP) IMP (or a simulated TCP-era IMP if that code becomes available) To speak to the TCP Internet on a simulated system that never had an Ethernet interface. BOTH are meaningful for ITS, but I think it's the latter that Lars is pursuing at the moment. It would be lovely if there was a common API for 1822 communications (whether to an external simulation running IMP code, or an internal simulated IMP that allows the host to talk to the Internet) p _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
