Hi all, I've been using version 2.0a of screen for a while now and I've been having a problem and would like to know if anyone else has encountered this. The problem occurs when I try to run screen with a TERM set to anything but vt220 (actually I've only tried it with TERM set to vt100 and twist). The problem is that screen is VERY slow when redrawing the screen (with TERM set to vt100) and is slow redrawing the screen in vi (with TERM set to either vt100 or twist). I thought that the problems may have been caused by the lack of delete line, insert line, or cursor motion capabilities on the part of the terminal, but the twist supports all of the vt220 functions. It seems to be especially prevalent when displaying the '~'s in vi or when opening lines above existing text in vi. I'm running now in 24-line mode on a twist with TERM set to vt220 and it seems fine, but I'd like to use the 72 line mode. I'm gonna look into it closer, but I was wondering if anyone has seen anything similar and had suggestions. This probably really isn't a bug, but I'd appreciate any input anyone has in any case. Thanks in advance, Todd Goodman tgoodman@bbn.com (617) 873-3866 P.S. - I'm running screen on an Ultrix V2.0-1. The twist is a VDT manufactured by the Facit Corp. which supports, among other things, a 72-line mode enabled by 'twist'ing the display.
