The host system is Ubuntu 15.10 and Linux 4.2.0-42-generic. I guess idle pattern detection missing or broken in simh for the particular guest OS. I'll have a look. and I can happily telnet in. Now I want to set up two SimH instances so that one DZ line connects the two together. I've read the vax780_doc.doc but I can't see how to configure an outbound connection. This is much better document in the top comment section in https://github.com/simh/simh/blob/master/sim_tmxr.c A snippet below. Let me know if that doesn't help. Line specific tcp listening ports are supported. These are configured using commands of the form: sim> attach MUX Line=2,port{;notelnet} Direct computer to computer connections (Virutal Null Modem cables) may be established using the telnet protocol or via raw tcp sockets. sim> attach MUX Line=2,Connect=host:port{;notelnet} Computer to computer virtual connections can be one way (as illustrated above) or symmetric. A symmetric connection is configured by combining a one way connection with a tcp listening port on the same line: sim> attach MUX Line=2,Connect=host:port,listenport When symmetric virtual connections are configured, incoming connections on the specified listening port are checked to assure that they actually come from the specified connection destination host system. ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
[Simh] A couple of newbie SimH questions
Hi all, as part of the preparation for the Unix 50th anniversary in 2019, I'm starting to get some Unix images up and running on SimH. What I want to get done is to recreate some of the early networking, in particular uucp and Usenet on top of it (with C-News). I've built 4.2BSD and 4.3BSD images as per the instructions here: http://gunkies.org/wiki/Installing_4.2_BSD_on_SIMH http://gunkies.org/wiki/Installing_4.3_BSD_on_SIMH and these run fine on SimH VAX 11/780 simulator V4.0-0 Beta git commit id: 7c5792e9 I've tried all of the SET CPU IDLE values and I can't find a value that lowers the CPU usage below 100%. Is there a compile flag that I need to set? The host system is Ubuntu 15.10 and Linux 4.2.0-42-generic. I've set up a DZ device with: set dz lines=8 att dz set dz 7b and I can happily telnet in. Now I want to set up two SimH instances so that one DZ line connects the two together. I've read the vax780_doc.doc but I can't see how to configure an outbound connection.
