(running under simh V2.9-11) I wanted to add the dz driver for multi-"terminal" support. But I'm a bit stumped figuring out how to rebuild rl2unix, let alone how to add the dz driver. (no rlconf/rl2conf file, although mkconf.c looks like maybe it knows about the rl2 if not about the dz) Is this do-able? Is the dz driver in the v7 image usable? -- mailto:rlhamil@mindwarp.smart.net http://www.smart.net/~rlhamil
