Let me jsut tell you the way I am set up: on the 20 I use terminal type VT100, in EMACS I use M-X Set Terminal Type$VT100 (well, actually, I have my EMACS.INIT set up to use this as default when on a dial-up line) On the Mac-side, I use VT100 in ANSI mode,8bits, no parity, XON/XOFF enabled (the last is very important when using 9600Baud lines) notice that I suspect your problem to be caused by not having XON/XOFF enabled. the Mac does not seem to be able to keep up with even 1200 Baud without it. An undesirable side-effect of XON/XOFF is that ^S, the Emacs-SEARCH command, and ^Q the Emacs QUOTE command are misinterpreted by the Mac. when in EMACS using ^S to SEARCH, Mac thinks that you just wanted to stop output, so nothing is displayed further until you type ^Q. Reason seems to be that the screen display can't keep up with the characters coming "down the pipe", so MacTerminal assumes when it sees a ^S, you want scrolling to stop NOW, rather than display every- thing already received into the buffer. So rather than just passing the ^S to the main-frame to decide what to do with it, MacTerminal tries to "second guess" the user. Sigh ....makes using EMACS a real drag. try it at 9600 Baud sometimes, and watch how Mac and 20 get confused when MacTerminal sends a ^S to tell the 20 to stop sending stuff - and Emacs on the 20 thinks you jsut typed a SEARCH-command.
