What's really strange is that version 3.8i which What you are probably experiencing is trouble with the 'typeahead' code for System V. This is one of the reasons that I eliminated this code when I added the terminfo/termcap support for uemacs. It is an unfortunate situation that there is no call equivalent to the BSD 'how many chars are waiting' call. Anyway, the typeahead can be eliminated (its in tcap and termio) to speed up the process. Alternately if you install my diffs for termcap/terminfo it will go away automatically. I'm trying to find a good alternate for System V, but its not easy. BTW, I've run into a rather strange behaviour between uemacs on a 3b2/300 and on a XENIX 286 machine. Under XENIX, you can edit a 100K-500K file with no trouble at all. Does take a while to read, but what doesn't? On the 3b2, uemacs just hangs reading the file forever (or at least more than 30 minutes for a 100K file. Thats all I was willing to waste). Anyone have any ideas? -l -- +--------------------------------------+-- St. Petersburg Junior College --+ | Lawrence F. Strickland | P.O.
