From: Marty Cohen <mcohen%NRTC@USC-ECL.ARPA> We are having a problem using CIT-220+s with EDT under VMS 3.7. The cursor movement is extremely slow - about 2 chars/second. The problem does not exist when using VT-220s, nor does it exist when using CCA EMACS on either type of terminal. In view of DEC's lawsuit against C. Itoh, maybe EDT checks to see if the terminal is a CIT and, if so, runs slow? Any help would be appreciated. We have carefully examined the setup on the CITs and it seems OK.

From: Richard Garland <OC.GARLAND%CU20B@COLUMBIA.ARPA> One reason EDT runs slow on certain terminals is that it uses AUTO-REPEAT as a way to slow things down if the screen is behind the keyboard: If you type stuff and the screen can't keep up, EDT turns off AUTO-REPEAT on the terminal until the screen catches up. This was really bad on VT101's where AUTO-REPEAT took 1/2 sec or so to turn off or on. (Not bad on a VT100). Mabe the CIT-220 is just slow about this particular feature compared to the VT220. DEC said (about 18 months ago) that they would both fix EDT and the terminal firmware. By now (V4.0) EDT may be fixed, and perhaps the vT220 is fixed (compared to the VT101). Rg -------
