No solution that I can see, but I'm curious as to why you're trying to
script this. I'm not saying there's no good reason to do it, just that
I can't come up with one. If you can provide more info on what you're
trying to accomplish, without divulging trade secrets, maybe someone
could suggest an alternative approach.
Bill:
No trade secrets involved. I use a periodic Control-T sequence to keep
active an SSH connection that will time out without input.
Now it makes sense. I'm using the .tcshrc from
/usr/share/tcsh/examples, so control-T is "twiddle" here (i.e.
transpose the two characters before the insertion point.)
However, I do
not want these unattended key sequences to trigger a line feed or it
could
cause the text on the command line to be inadvertently executed. What
made
an AppleScript solution so appealing is that the command can be issued
even
when Terminal is not the frontmost application.
So the problem is how to have the "do script" command of Terminal send
the
Control-T sequence (which is ASCII character 20) without also issuing
a line
feed.
About the only thing I can think of: if the last line of the contents
of the window matches the prompt string, don't send the "do script"
command. It's a slovenly hack, but it might be serviceable.
