Lines: 24 VT100 is certainly not ``optimal'' as it lacks character insert and delete (and line I/D is expensive because to do it requires setting and resetting the scrolling area; typically 14 to 18 chars to insert or delete one line). If you have a smart enough Emacs (e.g., my version of the AAA driver and display.c code), emulation of an Ann Arbor Ambassador would be particuarly good. (My Emacs AAA driver will fill the entire screen with any single character by writing 180 characters [at 30 lines/screen]; at 300 baud this is 6 seconds and at 1200 only 1.25 seconds! Admittedly you don't often want to fill the whole screen, but characters are repeated surprisingly often. Wouldn't it be nice for news to be able to put up all those `-'s people sometimes use, with only six characters? [To tell the whole truth, that's 180 characters without padding---but padding only occurs at >= 4800 baud.]) Other relatively good terminals are extended VT52 (H19), or just about any ANSI standard. But most of those don't let your editor delete 50 characters in one swell foop. (My H19 driver does, if you've got it in ANSI mode, though.) -- In-Real-Life: Chris Torek, Univ of MD Comp Sci (301) 454-7690 UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
