MacTerminal seems to require the vt100 termcap setting when being used on a
UNIX vax (4.2BSD). Our termcap file for the VT100 has neither line insert
nor line delete. Presumably MacTerminal's software is
capable of such operations. Is there a termcap file around for
MacTerminal that supports these (or other features)?
Without it, it makes editing on a UNIX system under vi more painful than
necessary.

I believe it came off of arpanet. In regard to Donalds Q, Im not sure it will do what you ask. Regarding Edward's comment this most definatly works at 9600 baud, I use it there often. The termcap is Am, I source the following file when I log in on my mac with macterminal. It works fine at any baud rate I've tried. hope it helps dave !uwvax!geowhiz!schuh # TERMCAP for macintosh. # # Am|macintosh|Apple Macintosh with MacTerminal:\ echo "setting up for macterminal" setenv TERM vt100 setenv TERMCAP ':am:bl=^G:bs:cd=\E[J:ce=\E[K:cl=\E[;H\E[2J:cm=\E[%i%d;%dH:\ :co#80:cr=^M:dl=\E[M:do=\E[B:ho=\E[H:kb=^H:kd=\E[B:kh=\E[H:\ :kl=\E[D:kn#4:kr=\E[C:ku=\E[A:k1=\EOP:k2=\EOQ:k2=\EOR:k4=\EOS:\ :le=\E[D:li#24:nd=\E[C:nl=^J:pt:se=\E[m:sf=\ED:so=\E[7m:sr=\EM:\ :ue=\E[m:up=\E[A:us=\E[1;4m:xn:' # # # END OF TERMCAP #

Sorry folks, but my TERMCAP problem still exists.
Thanks for the several replies I have gotten and the several new termcaps.
But perhaps I didn't make the problem clear.
Technical configuration:
MacTerminal 1.1, emulating a VT100, logged on to either a SUN
workstation or a VAX running BSD4.2 UNIX. Baud rate: a phone line at 2400
Baud or a direct line at 9600 Baud. Also tested at 300 Baud.
In the text editor vi, using TERMCAPS VT100 or am:
Here is the problem.
Suppose I have a full screen of text. I go to the middle of the screen and
delete N lines (with the command Ndd). The lines get replaced with the symbol
@
Just like above -- an @ in the first character position.
No No -- that's not what I want. I want the lines to dissapear and for the
empty space to instantly close up, to be replaced with new text scrolled in
from the bottom. This is how all intelligent terminals work. Only really dumb
terminals (technical term) don't have line delete and line insert so that they
have to stick in a @ and can't get rid of the empty space.
Now I know that the Macintosh can do better. Someone sent me a termcaps
that did do just what I wanted. So I know that Macterminal can do better.
Alas, that termcaps couldn't keep the screen info unscrambled, so it had to be
junked.
So, if you get @ signs when you delete a line in vi, then yours is NOT the
termcaps I want and you are defrauding yourself.
(I had better also say that yes, I realize I can get a new clean page
image by repainting the screen each time with a ^L, but that is a
pretty kludgy solution, very slow, and not satisfactory.)
One correspondent said I should simply junk MacTerminal and try his (public
domain) kermit. I will indeed give that a try as soon as I can.
Any other advice?
