yes, i was a bit unclear on that point. <blush>heh.</blush>
i'm trying to get my telnet session to behave as if
i was at the console: if i'm in VI i wanna be able to ^Z
to get to the shell prompt.
my telnet client is running on a mac, which has no
clue about suspend/fg/bg. :)
i want the remote (linux server) full-screen process
(mutt, vi, etc) to suspend when i send ^Z, despite the
fact that i'm using telnet, and not sitting at the
console.
hell, i just tried it from the perl debugger, which
doesn't even use curses/ncurses for its dialogue,
and ^Z blinks the screen there, too, with no
suspend signal being sent to the job.
"i want my control-Z!" (waaah!)

so, yes, all the settings below are from the server.
(ask a mac what an environmental variable is, and
you get deaf silence. comes from being a single-user
environment.)
