Normally, I use ^H as the erase key and DEL as the interrupt character. NN, however, will not do erase processing when it prompts me for filenames, newsgroups, etc. It will when I change the erase character to DEL and the interrupt character to ^C. Bug or feature?

We had the same problem with NN on our machine; in fact its the only complaint I had about the entire package! NN is a wonderful newsreader. Anyway, the one-line-fix below corrected the problem entirely for us. Apparantely there was a problem with the CTRL-H key being trapped by the key binding routines before it was identified as a back-space. Here is the fix. The below one-line-fix is in "term.c", in the function called "get_c()". Simply add the one extra line. It worked for us; we are running UNIX 5.2 on Plexus hardware... Hope it helps. ---- while (--n >= 0) { c = *cp++; #else while ((n = read(0, &c, 1)) > 0) { c &= 0177; /* done by ISTRIP on USG systems */ #endif + if (c == erase_key) goto got_char; /* FIX for ERASE_KEY problem */ any_multi = 0; for (i = multi_keys, mk = multi_key_list; --i >= 0; mk++) if (mk->cur_key) { ---- dean@coplex.UUCP Dean A.

I just realized during the weekend, that this was indeed the reason for the problems with the erase key on several systems: It was really a problem on a few terminal types such as Wyse50, where the arrow keys send single characters, and the left arrow key sends a back space! This can be work-around without patching the code by the following map command: map key left ^H which will map the "misinterpreted" left arrow-key back into the erase key. For some reason (another bug I suppose), the more obvious set erase-key left does not work! -- Kim F.
