I'd be interested in one of these critters, too, but have yet to find an emulator for my configuration (640K PC-XT clone, 8 mHz) that could handle 9.6 Kbaud, much less 19.2 Kbaud, without flagging. Last weekend, I (very informally) benchmarked two emulators I have access to. "MIRROR II" (commercially-available Crosstalk clone) came in at about 420 chars/sec and "PC-VT" (shareware, available from CompuServe) at about 520 chars/sec. These numbers were arrived at by measuring (on a UNIX system) the wall clock time required to execute "cp bigfile /dev/tty" where "bigfile" was a 20,000 byte file containing 250 lines, with 79 non-blank characters followed by a newline on each line. With all the new high-speed modems around, PC terminal emulation performance is becoming a bigger issue. I hereby offer to collect other people's experiences with high-speed terminal emulation. If you can beat these numbers on a PC-XT over a serial port, send me the speed you've measured (chars/sec, not baud rate), the name of the emulator you're using, what terminal(s) it emulates, and any other relevant tidbits you care to pass along. I'll summarize and post the results when the responses die down. >Are there >any out there which will allow me to remap the keyboard so that I can >map unix emacs cursor commands onto my cursor keys like I can with >Kermit, A different way to go would be to add the cursor positioning escape sequences (for the VT series, these are up = "[A", down = "[B", left = "[D", right = "[C") to your emacs startup file, if this is possible. That way, the keys work even if you're running on a real terminal. >as well as good emulation of vt100, vt102, vt200, tvi955 or >other popular terminal types?

It's also supposed to be on local BBS's. It seems very (maniacally, even) faithful to the goal of VT emulation. Its only drawback for your purposes is that it doesn't seem to run at 19.2 Kbaud (with flagging, of course). - Bob Lewis bobl@tessi.UUCP P.S. If you don't mind flagging, MIRROR II goes up to 115.2 Kbaud, as do many other emulators, I'm sure.
