I would like to make a small program I am writing react to single
keystrokes for option selection etc. To do this, I need to set three
things:

1)  the key must be passed straight to the program without the tty driver
    waiting for CR to be hit

2)  Backspace and delete must be passed through to the program (this
    may happen as a side effect of 1), I,m not sure.

3)  echoing if keys must be disabled - I want to be able to ignore 
    keys if I choose.

I suspect that these things are controlled by stty() or ioctl(), but
the man page for stty says please write a man page and send it to the 
Linux Documentation Project (something I'm clearly not capable of),
and the man page for ioctl says the options are listed in ioctl.h. This
leads a trail to termios.h which seems to list loads of options, but there
is no mention of which option does what.

I would be very grateful if someone already experienced in this are could
tell me how to achieve the conditions above (and how to cancel them once
my program exits). 

Please don't tell me to use curses, as some of the routines which I want 
to use don't exist (unresolved external during linking) although the man
pages (which seem to be copied from a sun) mention them. As a result, I
have decided to read terminfo within my own code and do my own thing.

Also, how does a program get notified if the xwindow it is in gets resized?
I see that vi and man both cope with this event admirably.

Thanks in advance,
        Steve.

     *** I have an OPTI motherboard with a "Chip-away-Virus" feature in the
BIOS.  A few days ago, I installed Linux on this PC with the "CD-boot" image from
the 1.2.0 Slackware distribution in the current Infomagic CD disk set.  "Chip-away
Virus" complained that there was a virus on my floppy, and I had to turn it off
in order to boot Linux.  Sigh.  I guess all of Linux is a virus, from the DOS point of

You also need the 1542 to send the startup command to the disk.  If the
disk has 'wait for start' enabled and the controller doesn't send it,
then the above error will occur.

Both Computerworld and PC Week have got it half right.  

The problem is that the conflicting stories coming out of Novell means that
it is next to impossible to figure out which half they've got right.

We do know:
-Torvalds was first contacted by Novell about the possibility of their doing
such a thing based on Linux 9 months ago, and Novell technical people have
asked him technical questions from time to time ever since.
-Ray Noorda, recently retired Chief Exec of Novell has been personally
involved in this project.
-Novell has demonstrated a product based on Linux.
-Visix have been contacted about using their Looking Glass GUI on this
product (we cannot get confirmation of a licencing agreement, although no
one is denying such a thing)

We also know that Novell desparately needs the world to adopt some sort of
desktop operating system that does not come from Microsoft.

I'd bet we will see an Expose or Corsair like product introduced by
September, although it may come from a "new" company spun-off from Novell. 
The marketing people at Novell seem really confused on this whole subject.

Cheers,  Bob.

Bob Young.

Of course, when you want to offer 'bbs' like services on your system, you
can offer several logins.  Document them in a small /etc/issue file, e.g.:

enter "bbs" for BBS
enter "nuucp" for anonymous UUCP
enter "slip" for SLIP connection

login:

That way, login acts as a multiplexor for the different access methods
that one can offer for the data accessible on the system.  Each method
has its specific advantages and disadvantages.

Subject: Re: Kernel panic on install
Date: Wed, 1 Jun 1994 13:46:41 GMT

I have some more to report.  I downloaded the install images for the 
latest Slackware release from sunsite and I haven't seen the GPF problem 
with any of the boot images I tried (bare, scsinet, cdscsi).  The 
Yggdrasil release still give the error, as near as I can tell it is at 
the point where it is attempting to determine what sound card capability 
the system has.

It sounds like the Yggdrasil and SLS releases must share something in 
common that the Slackware release doesn't.  I have a bug report filed 
with Yggdrasil on this, and hope for a quick answer, if not I'll return 
the Yggdrasil CD and manual and order Slackware.

You might want to try this approach to see if your system will boot for 
you as well.  You'll need GZIP.EXE RAWRITE.EXE and at least one of the 
above mentioned boot images for what ever size media you are using for 
your boot drive.  Also you will need color144.gz for 1.44 Mbyte floppy or 
colrlite.gz for 1.2 Mbyte from the rootdisk sub-dir.

Hope this is helpful.
Burt

Thanks to everyone who email me about the undoc feature of fdisk.

I've discovered one thing; you cannot set a partition active if you have
already booted from a bootable drive( drive C is set active and booted from).
My problem was in trying to fdisk /mbr from the C: drive to the D: drive.

I had to create a bootable floppy, change my cmos to make the linux drive
the C: drive, boot from the floppy, then run 'fdisk /mbr'. Then
reconfigure the linux drive as drive D: so I can transfer the dos files
from the new drive. ( what a pain!! )

Thanks to all

Many of the newer generation of SCSI drives have a jumper which enables
(disables) spindle motor spinup on power-on. In large arrays of drives,
such as in a RAID, motors are spun-up sequentially; staggered so as not
to overload the power supply. Check to see that the spinup-on-power jumper
is configured properly for your drive.

Ok.  So lets say that we forget that Function Keys exist, then.  For the
novice user, we will have to have some way of sorting through things 
_easily_.  I don't usually consider remembering 30 different control-
whatever sequences easy.  Faster, yes.  Actually, now that I think of 
it, when I use WP 6.0 for DOS (not often!) and need to do something and 
I don't want to use the mouse, I hit Alt-F and start to look through 
the menus with the arrow keys.  Could we do the some except replace 
the ALT-F with the ESC keys?  Telling a novice user that all he has
to do is hit ESC and arrow around to do anything he wants will surely
make him think before canning Linux because it is way too complex.
For the word processing part of it anyway.

By enabling joe with mouse support, that will entail 'shutting off' 
selection temporarily.  The cut feature should place it's text in
the same place that selection stores it.  Is this what you mean by 
'(from the selection code)'?  This will allow pasting to other VC's. 
I like that.

have no clue where I would start.  

: We're always looking for volunteers BTW.
How many is 'we'?  In other words, how many people have said that they
will hack on the code?

I might suggest, however, that this project might be suited better for
coding in c++.  I've been coding in it for a couple of months and 
think that the modularity of it is quite outstanding.  It would make
it easier to do this, I think.  This would mean scrapping some of
the joe code, but most could be easily converted to a c++ type of
thing.  Ideas?

That crap merely monitors BIOS writes to the MBR on your hard drive.  it also
monitors writes to the boot sector on floppy disks, but not on the hard drive.
(Therefore viruses that infect the boot sectors of partitions on hard drives
like Form evade this "protection")  I would call it much more of an annoyance
that anything else.

I would much rather say that all of DOS is a virus, from the Linux point
of view, than vice-versa. :)
