When I try to type a ctrl-f (forward-one-character), or most any other ctrl character, everything is OK. But when I try to type ctrl-@, or any of the ctrl characters involving a number key or shifted number key, I get the number entered into my text (whether I used shift or not). I am using emacs, and have tried this with both RR 10.3 and VersaTerm 4.0. For example, to set the mark, the command is ctrl-@ (ctrl-shift-2). This works fine on the GraphOn 225 I am currently using, but on my Mac is enters a '2' into the text, and nothing else. Any ideas? Jay Boisseau jay@emx.utexas.edu

IMHO it is easier than C-@, anyway. I know this really doesn't answer the question of why these terminal emulators can't send a C-@, but at least you can set the mark without doing M-x set-mark :-) -- ---------------------------------------------------------------------------- Michael J.

In article <14666@ut-emx.UUCP> jay@ut-emx.UUCP (Jay Boisseau) discovers
that his terminal emulator doesn't understand ctrl-@.
There really isn't a standard for keyboard->control character processing.
You might try ctrl-space (this works on my emulator because I wrote
it myself). One problem is that ctrl-@ and/or ctrl-space are probably
sending the <NUL> (000) character, which is often eaten by intervening
hardware/softare.
If you use Emacs, you might find binding set-mark to a function key
offers a longterm solution.

I don't know of a way to get a chr(0) out of the keyboard without using a specific program to do it. You can, however, get a Control-^ using the most recent version of ResEdit. This is the way I do it: 1. Open a copy of the System file 2. Open the KCHR resource. You should see one labeled "US" for domestic units. Open it; its ID should be 0. 3. If you press the Control key, if you have an ADB keyboard, the keyboard template would change. You'll see valid what the key combinations of Control-A, and so on would give you. The Table list would change from 0 (default), to 7. I have an SE and am using System 6.0.2. 4. To change a Control-6 to give you Control-^, select the 2nd to the last square of the 2nd column from the left of the ASCII keys matrix. _________________________________________________ | Table | | ASCII key- list | | keys board | | matrix matrix | | | | | | Keyboard facsimile | |_______________________________________________| Drag the square to where the 6 is on the keyboard facsimile. 5. Quit ResEdit and answer YES when the dialog box comes up. Alternatively, you can create another Table that is used only when Control-Shift is pressed. What you need to do is to select the table that's associated with the Control key by clicking on it in the Table list. Go to the KCHR menu and select Duplicate Table (you won't have to re-enter all those control keys later on). Change Control-Shift-6 to reflect its ASCII counterpart. That's it. Unfortunately, if you assign ASCII "0" to Control-Shift-2 or Control-2, pressing it on the Mac keyboard will get you NOTHING! It really gives you a "NUL" key. I haven't found any way to get ASCII "0" to come out by using the KCHR resource. Another gotcha with this "fix" is that I haven't tried it on a Mac without a Control key. I hope this helps a little bit. If anybody out there in Netland knows how to get an ASCII "0" from the keyboard by using the KCHR resource, do tell.

Well, VersaTerm-PRO 3.0.2 handles control-space as ASCII NUL, which is what control-@ is supposed to emit. Note that this is a vt100ism. I would be really surprised if VersaTerm 4.0 doesn't do the same thing. The only other "legal" shifted control character I can think of is control-^, which works fine in VT-PRO. VT-PRO has a built-in keyboard remapper, so you don't have to fool around with ResEdit, as others have suggested. Charles Allen cca@newton.physics.purdue.edu

...In reply to the original question (How to set a mark in emacs, using a Mac II as a terminal emulator): Try 'Command (Apple?) - space' rather than Control-@ or Control-Space. I hit this by accident once, and sure enough, it set a mark! I don't know if the goat I sacrificed on the previous sabbath had anything to do with it... I use NCSA Telnet on a Mac II, which emulates a vt220, and this works for GNU-Emacs 18.53, and for Gosling Emacs on VMS (don't know the release #) Hope this helps.

It is easy enough to fix by choosing "Reset Terminal" from the menu item. I have a hunch that a special sequence of control characters is toggling this mode. Here at Columbia we have written a full-screen program that consistently pops the Mac NCSA Telnet 2.2 into this mode. We would like to avoid this, so does anyone know what exact control codes toggle Telnet into this mode so we can program around it?
