[HECnet] DDCMP over asynchronous emulated lines on simh 4.0

From: Clem Cole <clemc at ccc.com> This line had me chuckling. DZ were notorious for being lousy at supporting modems because they lacked all a number of the needed RS-232 modem control lines. Yeah -- I remember being dismayed that it didn't even have enough to power a serial mouse. That would have been stupid fun (as it already was on the PDT-11/150's modem port). I don't know how happy the mouse really would have been talking to the PDP-11 over ~100' of cable, but that's part of what would have made it stupid, and therefore, fun. John Wilson D Bit
