Thanks Hal for help with the video.
I'm also having problems with my printer and modem.
The printer is an old HP DeskJet 400. I've used printtool and gone through
all of the steps, but when I try to print the ASCII test page the cartridge
light on the printer blinks and nothing happens. I've seen this happen with
the driver provided in Windows also. Just a crappy driver. The original
has to be downloaded from HP.
I'm also having problems connecting with my generic PureTek K56Flex external
modem. According to linuxmodems.org this modem is compatible. I've gone
through everything with the RPS dialup configuration tool, checked the
physical connection by using _echo ATZ++ >/dev/modem_ (lights were
blinking), but still no connection with the RH PPP dialer.
Any solutions? I'd be glad to post additional info if needed.
Thanks.

You're ignoring the one about management. Consider that many factories
operate 24/7, which means they never shut down the terminals and the
"application" runs constantly. When you upgrade the application, the
terminals are still running it. You have to get all the clients to shutdown
and load the new version.
Yes, you could write a script to connect to the machines and kill the
processes and restart it, but what if those terminals are in use when you do
this?
The web based solution works well, because once you've updated the
application, the next time they load a page it uses the new version
automatically.

I once noticed that there is a free 1GB partition on my Linux PC at
home, so I one day I installed Solaris 7 on it. The install program
will create a Solaris disk label on that disk and the disk slices used
by it will all be contained within that partition.
Dual-booting was done easily with LILO. It was more complicated in my
case because the disk that Linux and Solaris were on was not disk that
the system boots from initially. However, if you have just one disk,
there will be no need to additional LILO tweaks.

Yeah. Too many changes in temp and volume are distracting,
and classical does a lot of that. Baroque is more even
and steady and therefore (to me anyway) less distracting.
Chant can also be okay as background, as long as it's
in a language I don't know. Someday when I learn Latin,
I probably won't be able to play chants as background
anymore.

It probably couldn't, when laptops were introduced.
These days you can get a laptop that will really perform,
if you're willing to pay money. That wasn't always so.

What I want is a static IP so I can telnet into my
home system from work (or, for that matter, from
wherever)... but I'm not sure I want to pay for
that just yet.

The motherboard goes with the processor, but I already
explained that most of what I do isn't processor-intensive.
My PII/233 is fast enough and will continue to be fast
enough for a couple of years yet. But I had to buy more
RAM and a second hard drive and am going to be getting
my third keyboard soon. If I were getting a new system,
I'd be thinking along similar lines in terms of expansion
path: get something good enough that in five years it
will still be able to function.
The other thing is, Duron is a cheaper option than
almost anything new, except K6-2, and K6-2 just won't
have the performance in two or three more years; I
want my PC to last longer than that, if nothing else
because migrating a multiboot system to new hardware
is a serious pain.

Redhat and Mandrake are designed to be newbie-oriented.
Which, in itself, is not a bad thing.

I think HP might sell some AMD-based systems.
Dell will actually sell you a PC with linux pre-installed,
which is a relatively major step IMO, since Dell is one of
the "big boys" in terms of selling package-deal systems.

ADB is a type of DIN connection, similar to PS/2 on first glance,
but the pins are not in the same places. Mac keyboards and mice
use them.
Even assuming you can get a switchbox that can do the physical
conversion between ADB and PS/2 (which you definitely want to
check rather than taking for granted), keymap issues might arise
if you want to use the same keyboard between Mac and PC systems.
The letters are all in the same place, but there may be issues
with things like backspace, del, delete, ctrl, alt/meta, option,
command (clover), win/meta/alt, pgup, pgdn, prtsc, break, and
so on. Could be weird. Not to mention numlock if you use that.
Something to think about before you jump in with both feet.
Even if it "works", you could have some strange "which key do
I use for that again?" situations.
Do Mac and PC monitors receive the same signals?

I have a tangentially related question...
Most of the time I use 640x480 or 800x600, but if I wanted
to zoom in a bit closer (say, to mess with a simple image
more carefully)... what happens if I put something like
"320x200" on that list? Will I hurt anything trying it?

Slightly confusingly, MIDI playback devices normally do not
have the letters "MIDI" in them; they usually go by "MPU401";
look for that. (It may be that that isn't installed either,
in which case I don't know enough to coach you further.)

When I used rpm to install harddrake (to facilitate getting my
ethernet card working quickly and easily), one of the dependency
errors I got was that alsa was required, so I had to install
that first. So I guess that Mandrake generally uses alsa.

How they're priced varies considerably, but they are bargain-basement
and don't forget it. The one we have at work runs okay (Win98), but
it looks and feels very proprietary, worse than the Compaqs we've
got also. (NO expansion slots, weird buttons on the keyboard,
the monitor and mobo are inside the same integrated case with
translucent blue plastic on the outside, highly bizarre wheelmouse
with a wheel that doesn't work right and confuses people because it
looks like a button and the actual buttons aren't visible, being
coincident with the body of the mouse...) I imagine, however,
that different models of eMachines are not all the same, and I
don't know anything about the 633is specifically.

Okay I have to ask: are you just wearing your keyboards out really quickly,
or have you somehow found a way to interface using three at once?

Hi,
I've been using Linux for quite some time and have never been able to get
the RH PPP dialer included with RH7 to work reliably, you may try another
dialer.
I have KDE installed though I use gnome, I use KPPP to dial the Internet, it
always works great.
Have you tried to use minicom to dial out?
I assume you are using the correct ttyS port?

Regarding the ttys port,
It should be on ttys2, it is on com3 in windows
setserial returns this message-- /dev/ttys2: Input/output error
the same goes for statserial-- Input/output error
Also, the modem is not included in pnpdump
It appears that there may be IRQ, DMA conflicts. I'm completely in the dark
on port conflicts in Linux (newbie). Any further help with this would be
great.

Be serious! There are several ways to block this -- no default (0.0.0.0)
route on the terminals is the one I used when setting up web-clients in an
electronics (automotive elec) facility.
How about having the firewall deny outgoing packets from the shop floor's
subnet?
There are numerous, effective ways to restrict the floor systems to showing
only work-related items. Many manufacturing facilities require that a
terminal show only info related to the STEP PERFORMED AT THAT POINT, and
not just general work info.
HTML control with PDF documents is a great way to do centralized document
distribution in a document-controlled environment.
