Well, detecting connection drops is certainly possible. Numerous other devices which use the "Telnet terminal multiplexer library" do this. There is a significant body of code at https://sourceforge.net/projects/dps8m/ which is organized in a reasonably complicated way. I unpacked the dps8.tar.gz tarball, but it isn't immediately obvious which module implements the multiplexer device. Please point me at the module which uses the sim_tmxr library and I'll suggest ways you can detect/manage dropped telnet connections. - Mark _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
