In localhost.freebsd.questions you write:

OK... round two.  I diffed your stty and my stty, and here's what I got:

First, my stty (2.2-STABLE, 6.06):

        eol2 = <undef>; erase = ^H; intr = ^C; kill = ^U; lnext = ^V;

        stop = ^S; susp = ^Z; time = 0; werase = ^W;

Here are the options which differ:

-extproc
ignpar
-oxtabs
parodd
-hupcl
cstopb
erase = ^H

Another thing I'm wondering about is what setty returns.  Apparently
this can influence things, although I'm not entirely sure how.  Here's
my setty:

{foo} ~ 1:44 ttyp4 > setty
iflag:-inlcr -igncr +icrnl
oflag:+opost +onlcr
cflag:
lflag:+isig +icanon +echo +echoe -echonl -noflsh +echoctl -flusho +iexten
      -extproc
chars:

Another useful and interesting command may be echotc, settc, and
telltc.  Here's what my terminal returns:

        Tcsh thinks your terminal has the
        following characteristics:

        It has 80 columns and 24 lines
        It has a meta key
        It can use tabs
        It has automatic margins
        It has magic margins

I hope that this helps...
