In Rick Thomas's original posting to mod.sources (444 at genrad.UUCP) of the
termcap for crosstalk, he gives both termcap and terminfo versions.  He uses
the terminfo version himself and it seems to work.  How ever, I found a
problem with the termcap version.  I called Rick and we traced the problem
to a flag in the termcap entry.
Here is a corrected termcap entry for crosstalk.

------------------------------------------------------------------------------

A bug was found in the recently posted termcap entry for the crosstalk program
emulating a vt100.  The problem amounts to double newlines being generated in
vi when a line is longer than 80 characters.  The following is the original
posing and a correction.

The problem is in the "xtalk" entry.  The "am" auto-margin flag should not
be turned off as shown above.  The following is the corrected "xtalk" entry.

d1|xtalk|IBM PC with xtalk:\
	:sc@:rc@:cs@:xn@:al=99\E[L:dl=99\E[M:tc=vt100-am:

I hope this helps any other confused termcap users out there.
