This is why I tested out all those actual cables, exactly for this reason, to have a known good reference that anyone can buy off the shelf with no more possible mystery about the wiring. Everything is done all in the one part. No gender changers, no null-modem adapters. No possible mysteries. If you get any of those 3 "ideal" cables, then the wiring is correct. If you get any of the other cables, the wiring is *still* correct, just only for software flow control (which is everything but HTERM).
By "test" I don't just mean I used them and they appeared to work. I mean I actually mapped out all the connections with a continuity tester. Same goes for the usb adapters. I actually tested those too so they are known good references, not just typical examples. Since it sounds like you have 2 usb adapters, you can prove them and eliminate a whole lot of variables at once by just hooking them together (with a null-modem adapter) run dlplus on ttyUSB0 and run TpddTool on ttyUSB1 to load and save files to dlplus. Copy files in both directions and then "cmp" against the originals. Assuming that produces clean copies, that proves out and eliminates the linux computers motherboard cpu ram etc, the os, the usb-serial drivers, the usb-serial hardware, and the dlplus software. -- bkw On Jan 13, 2018 1:03 AM, "Peter Vollan" <[email protected]> wrote: > TS DOS.
