Another win for Adam Thompson! And another way I can fool my co-workers into thinking I'm as smart as Adam.

Good call. Now when I log in, TERM=xterm. However when I size the PuTTY window to 100x55 and type a long command, it still wraps it at 80 columns back to column 1 on the same line, which is not desirable. The BASH version is 4.1.11(1)-release, and the environment shows COLUMNS=80 and LINES=65 -- different from before when COLUMNS=80 and LINES=34. Try a different termtype? Any other ideas?
That's because SIGWINCH doesn't make its way through an iLO connection; regular X11 or SSH connections work fine, right?
If so, then the way to deal with it is the old "eval `resize`" technique. (More correctly, "eval $(resize)", but both work.) Note that this command is supposed to work in any shell, the resize command auto-detects whether to emit sh(1) or csh(1) lines. If you're using a non-standard shell, you may have to tell resize(1) what to emit.
Alternately, "stty cols XX rows YY" should work as well.
In some corner cases, you'll need to use stty(1) first, and then resize(1) as well (or just unset $COLUMNS and $LINES).
Nowadays, it should be reasonably safe to put this in /etc/profile:
eval $(/usr/bin/resize) && stty cols $COLUMNS rows $LINESas all modern VT100-ish or ANSI-ish terminals respond to the escape sequences resize(1) emits, and those few that don't no longer enter weird modes as a result of them, and resize will time out in (IIRC) two seconds.
Read the comments at the top of https://ohse.de/uwe/software/resize.c.html for some background on why this is such a PITA... some software only queries the kernel ttyios for terminal size, some query the environment variables, and some query the remote terminal directly.
