[HECnet] Vt100 tester

From: "Brian Schenkenberger, VAXman-" <system at TMESIS.COM> Beware of the versions of VTTEST out there. Someone in VMS engineering had tried to make it DECC compatible and horked it completely. I believe that the version I have at the DECUS Library Compendium (DECUSlib.com) Freeware CD version 4 is the only properly working version. Don't dowload any try to use any of the later versions. Not like I'm *looking* for trouble here but ... I was horrified by how badly Ersatz-11(my PDP-11 emulator)'s VT100 emulation (which I've always thought was good) was failing test #1 (Test of cursor movements), and then mystified when I logged the output and saw it depending on behavior that I'm 100% sure I tested on real VT100s centuries ago and convinced myself they don't work the way the test expects. Then I got sidetracked with mounds of other fixes... But today's exchange reminded me to unearth a real VT100 and schlep it out within cable's reach of something which can telnet to great-escape.tmesis.com and ... OK yes I have to investigate and fix my handling of setting tab stops and of course I don't bother with smooth scroll at all (it's not reasonable in text mode on the MDA/CGA/HGC/VGA) but other than that I was *delighted* to see the real VT100-AA (with AVO) fail the tests in exactly the same way as E11's VT100 emulation. Am I insane, or do I have a counterfeit VT100 (would Eli Heffron steer me wrong in ~1985?) or have these tests really not been tried on a plain ol' VT100 in eons and there's bit rot no one has noticed? Or some fourth option I'm not thinking of? John Wilson D Bit
