If this is the same type of cable that you would use to connect a
modem to a PC, then you must deal with the following situation:
(1) The PC expects to talk to a modem at the other end of the cable.
(2) The terminal *also* expects to talk to a modem at the other end
of the cable.
Note that both devices want to talk to a modem. You must do something
to satisfy this yearning.
What you need, therefore, is little item called a "null modem".
The null modem consists of a small plastic block with a female
connector on one end and a male connector on the other end, with
some tricky wiring inside. You can buy a null modem at a Radio Shack
store, or from various vendors such as BlackBox or Digikey. They are
available in either 25-pin or 9-pin styles.
(Pedantically speaking, the 9-pin D-shell connector is a DE-9, but
this detail is usually fudged.)
Attach the null modem to one end of the cable between the PC and the
terminal. (For a simple asynchronous terminal, it probably doesn't
matter which end of the cable.)
Then see if the terminal can communicate better with your FreeBSD Unix
system.

The Netgear FA410 is a 16-bit PCMCIA card, so its maximum data transfer
rate is roughly 20Mbit, not 100. If you need something faster then
you'll need a different PCMCIA card. Out of curiousity, what's the
exact data transfer rate you get when the card/switch/OS report running
at 100Mbps?

Hello,
Check out mwave.com
http://192.216.185.10/mwave/Index.hmx?
I have been ordering from them for a couple of years. Excellent prices,
good hardware selection. Shipping is fast. I have ordered Monday morning
and received it Wednesday, shipping UPS ground. But then I'm only one state
away. I've never had to RMA or return anything to them, so I don't know how
they are in that area. I've had 4 or 5 friends, at least, order from them
also with no complaints. Don't know if they give recommendations on Linux
supported hardware or not. I have been using Linux for around 4 years, so I
know if the hardware I'm buying is supported.
Memory I don't buy from them. I order memory from Crucial.

An excellent suggestion, and it looked like a promising approach - but it
didn't help. My PCI devices are all camped on IRQ 11 (same one they use
in Windoze and Mandrake 7.0), so I still haven't been able to identify
any conflict on IRQ 12. Neither /proc/interrupts, nor lspci, shows
anything on that interrupt.
I see someone else posted a similar RH7.1 problem today, and Kudzu was
identified as the culprit; I don't think Kudzu is installed on my
machine, but I'll check.
Obviously PS/2 support has gotten badly screwed up in the 2.4.x kernels.
grumble, grumble...

Try looking at www.linux-usb.org. They list several USB CD RW
drives that work with 2.4 kernels. The 2.2 kernels only have
limited USB support, so without patching or upgrading, you won't
be able to use USB CDRW drives.

Fire up minicom and see if it can initialize the modem correctly, using
/dev/modem. If not, either the drivers are not installed, or they don't
work for your model. What model of modem is being reported on the PCI
bus (use lspci -vxx) ? Are you sure your telephone cord is good and
plugged into the line rather than the phone port of the modem (hey, we
all have bad days) ?

I got two APC UPSs off eBay. Great deals, work just fine. I recommend
them over other brands.
I first got a new SmartUPS 700 for $197.50 delivered. I later
transferred that UPS to my wife's 486 computer and got a used SmartUPS
2000 for my 650 Athlon and 19" monitor. It will power my system for a
couple of days before the battery will run out.
I prefer the SmartUPS series because the output waveform is much more
like what the power company delivers than their BackUPS or BackUPS Pro
series. In fact, I have powered AC blower motors and a hair dryer from
the SmartUPS 2000. I got that large a UPS so we will be able, with the
solar panels I have, to have an independent power source (we used to
live in rural Colorad and generated our own electricity).

For the primary purpose of a UPS, to protect the data on the machines,
power only the machines and the monitor. That will allow you to

You haven't looked in the right places.
On the APC website, try,

There are 7 choices of Linux software.
Also try Network UPS Tools at http://www.exploits.org/nut/ .

Use eBay. Just be thorough and check out each seller carefully. Email or
call them BEFORE the conclusion of the auction.

Aha! I finally found something that fixes the mouse! I added "noisapnp"
to the boot parameters (in lilo.conf, in my case), and the problem was
solved. Whether this creates other problems remains to be seen...
So it appears that something in the 'isapnp' initialization in the kernel
is disabling the mouse. Don't know what (yet).
This isn't a permanent fix, but I can live without PnP support a lot
better than I can live without a working mouse.

I had a similar problem with Mandrake 8.0, which is much the same kernel.
Turning off plug-and-play support (add "noisapnp" to the boot parameters
in lilo.conf) seems to fix it. An interrupt conflict is probably a more
likely explanation for your problem, but if that isn't it, you might try
the same "fix" I did.

I have tried the sample settings that match my manual;
# 800x600, 75.0Hz; hfreq=46.875000, vfreq=75.000000
ModeLine "800x600" 49.50 800 816 896 1056 600 601 604 625

The 800x600 is OK, but the 1024x768 needs stretching to fit the screen.
I don't want to use the screen adjusting buttons as I want to swap between

Some USB CD-RWs are supported. Check http://www.qbik.ch/usb/devices/
and read the notes. You should probably use kernel 2.4.5, since the USB
Mass Storage drivers that CD-type devices use are a little more mature
there than in the 2.2.x backports.
FWIW, the USB CD-RWs I've seen are coaster factories even under
"supported" OSes like Lose9x and MacOS 9. SCSI or FireWire is the best,
but ATAPI is the cheapest and probably the best price/performance ratio
for light duty.

Hello,
We are currently looking for an embedded, low power (PowerPC?) SOC/SBC
capable of (a) running Linux, (b) with integrated Ethernet transceiver
and (c) support for either Bluetooth or 802.11b. Or simply a PCMCIA
card slot. :-)
It would be used inside a server, so that, upon being wirelessly
instructed to do so, it would, via "normal" Ethernet, wake the server
up using standard Wake-On-Lan.
Can you give me a hint on where I might find such a device?
Thank you for your attention.

Hello,
I used to have RH 7.0 running the 2.2 kernel, and then I upgraded to 7.1
with the 2.4 kernel. Both of my CD drives (IDEs) were working under
/dev/scd0 (the reader 0,0,0) and /dev/scd1 (the burner 0,1,0). After
the upgrade, kudzu found my CD-ROM drive for some reason and added it to
/etc/hosts even though it was already set under /dev/scd0. It is no
longer recognized as being SCSI. My CD burner was left at /dev/scd1 and
is still recognized as a SCSI device, but is now at 0,0,0. cdrecord's
scanbus option no longer can detect my reader so I can't make disc

All,
I've read every post I can find on this, but none of the solutions seem to
work for me. I've got a vanilla RedHat 7.0 install with pcmcia-cs-3.1.26
and the ORiNOCO 6.06 driver from Lucent installed as a module, kernel
2.2.16, and a Dell OptiPlex GX1 desktop.
Any attempts to transmit out the wireless card give me a kernel error of:
Jun 2 18:42:03 ramcharger kernel: eth1: Transmit timeout.
Jun 2 18:42:43 ramcharger last message repeated 4 times
Jun 2 18:43:53 ramcharger last message repeated 7 times
Jun 2 18:44:13 ramcharger last message repeated 2 times
and
Destination Host Unreachable errors from the ping.
Most of the solutions seem to indicate that it's an interrupt problem so
I've tried excluding every interrupt available one at a time with no
success. I've turned off every possible function on the board - no sound,
serial, or parallel ports - to maximize the number of available interupts
with no success. I've also tried setting PCIC_OPTS="irq_mode=0" and with
that, the module fails to initialize altogether with a "ResourceIRQ:
Resource in use" error.
I know the card(s) work because I've tried it with 2 different laptops.
I've also been lucky enough to borrow a separate PCMCIA adapter (with a
completely different chipset) and ORiNOCO card and it gives me the same
error (and yes, I've switched PCI slots too).
I'm running out of things to try. Any suggestions?
