Subject: Frozen Terminals
I would just like to add something to Mr. Brown's article
terminal lockup. The problem of "receive flow control

Having this parameter set by the stty command tells
that any character sent from the keyboard, not just
can be used as the signal to restart output once it
has been stopped
by typing a Control-S. This restart character could
The ixany option could be set up globally either by
the line "stty ixany" in the file /etc/profile,
or by including IXANY in the "final-flags"
third field as separated by the # sign) in the /etc/gettydefs
file. You can include this in all entries in the gettydefs
file or just in selected ones.
If you don't wish to make it global then you can just
"stty ixany" line in selected users' .profiles.

Good point. However, even though we use ixany on all
our lines, we still encounter some flow control problems.
that whether ixany is totally effective depends on how
the driver is implemented and how other communications

I have a question which has been bugging me ever since
I started with
UNIX -- what is the significance of "foobar"?
I would be
eternally grateful to be enlightened in this respect!

As the story came to me, "foobar" originated

Dear Sys Admin Staff,
I just received your second issue, (my first look at

I read the letter written by Russ Hill in issue 2, and
while I will
agree with some of his points, it was his last paragraph
me. In it, he states: "If this mag is going to
be for sysadms
then realize your readers are SYSADMS! and they know
all about shell
scripts and they know how to port programs. Please in
talk about real sysadm issues!!!!"
I have worked with various platforms such as Sun, Harris,
NBI, and have worked with UNIX (BSD and SYSV) for about
6 or 7 years.
In that time, however, it has never once been required
of me to port
a program. I would find an article on this to be very
and informative. Also, while I have worked with shell
scripts, I am
always interested in seeing what other people are doing.
Please keep your magazine a technical one, but please,
that because a technique has been around for a while
knows it inside and out. I'm sure there are other individuals
there who share my opinion, and would like articles
on not only the
latest and greatest, but also the tried and true.
Thank you for your time, and for a great magazine.
