*** REPLACE THIS LINE WITH YOUR MESSAGE *** I don't understand all the complaints about PC-VT that have been posted recently. The basis of these postings is a "vt100 emulator test program" (which I admit I haven't tried), as opposed to actual use of PC-VT in the real world. My experience is that PC-VT is the only PD emulator that I have found that works correctly when I log into a UNIX system and use the vi editor. On the other hand, I have been unable to usefully use vi with any of the terminal emulations claimed by Procomm (at least version 2.3). Most of these emulations "sort of" work, but none is as complete as PC-VT.

Unix has a list of descriptions (usually called termcap or terminfo) for many different types of terminals. If you tell vi that you are running a vt100, it uses the description of a vt100 to control your terminal. These terminal descriptions, unfortunately, are by no means perfect. Any system administrator (and anyone else with appropriate permission) can go in and redefine what a "vt100" is. Thus, if PC-VT works fine, this only means that the vt100 terminal description matches what PC-VT expects. It does not say anything about the ability of PC-VT to really emulate the vt100. The vt100 test program referred to earlier was specifically designed to test terminals and terminal emulators with respect to vt100 comnpatibility. While it is surely not a complete test, it does provide a better way of assessing vt100 compatibility than using vi.

PC-VT worked with VMS before VMS had a terminfo style facility, and when
that was added to VMS it went on working just fine. This doesn't prove that
it is a perfect VT100 emulation, but does speak for PC-VT's ability to handle
normal VT100 escape sequences.

Procomm lost reverse video for some reason, and PC-VT is ssssssllllloooowww updating the screen. (Watch clear-to-end-of-line write spaces to the end of the line; you can see the cursor move. Makes ANSI.SYS look fast.) And my status line programs (define lines 1-23 as scrolling area and use line 24 as the status line) never worked right in PC-VT or PROCOMM. Kermit works quite well, thank you. ++Brandon -- ---------------- /--/ Brandon S.
