Since there was never any Ethernet adapter for the KS (it was a massbus device), I believe you must speak DDCMP, which we used with KMC's, which would do 56Kbs. There was a slower adaptor for 9.6Kbs, but the name escapes me at the moment.<o:p></o:p></p><p>I've had little trouble with Tops-20 V7 DECnet; that is, once I got it to working. When I was modifying FAL/DAP to accept anonymous transfers, I and and others beat on it quite a lot to wring the bugs out. These regression tests were against another 20, RSX 11M+ (or whatever MIM:: is running) and a couple of Vaxen. The operating system level code was robust; no crashes.<o:p></o:p></p><p>We found some interesting bugs; I think my favorite was RSX wanting all capital letters for months and Tops-20 sending capitalized months, so file dates got messed up. There were others, but they took some effort to remediate; so, not so favorite...<o:p></o:p></p><div><p class=MsoNormal>On 2/25/20 1:38 PM, Rob Jarratt wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><span style='mso-fareast-language:EN-US'>Mine has been built to be portable (it is in C).
