Date: Thu, 28 Sep 2000 17:05:43 +0000
I plan to acquire a pcmcia tfm560e modem card, which has a cirrus logic
chipset.
Does anybody know if this modem works under linux ???
Browsing the internet I've seen that there are so many pbs with
winmodems and I wouldn't like this one to be one of them...
Or anybody would have a suggestion to make for a cheap and easy to find
modem that works under linux ?
Thanks,
Sylvain.

If security is not a problem a solution might be to set the suid-bit on
the program:
chown root whatever_the_name_of_the_program_is
chmod u+s whatever_the_name_of_the_program_is

It's probably a Winmodem (software modem). Although some
Winmodems can be persuaded to work in linux, I don't think the
Sportster will. Check out http://linmodems.org/ to see if your
model is supported in linux. If not, you'll have to replace it
with a hardware modem. These are somewhat more expensive than
software modems but tend to perform better as the cpu doesn't
have to pretend to be a modem in order to make it work. When
shopping around, look for a model that supports non-Windows
systems (eg, DOS, OS/2 linux) as these will be true hardware
modems.

yes but there are obviously not going enough data over the bus?!
Therefore i took raid0 as the bus should be quicker than the disk
and so both disks could be written nearly simultaneously
(disk - cache is big enough)

I recognize this. Same problems. Same tryouts, same results. I choosed
to let PnP disabled. Also under Win95: ISA, no irq, only an I/O address.
I use my 3c509b to connect to my cable-internet provider and this
happens to go well (both win95 & Mandrake 7.1 Linux). I have an (but how
to prove ?) idea that the card functioned somewhat better under PnP
(fewer hickups of that awesome Netscape), but indeed no Linux then.
If you use your card to connect to a network, I have no answer for you.

Subject: HP 7200i CD-Writer won't work on one system, will in another!
Date: Thu, 28 Sep 2000 15:32:17 -0400
About 18 months ago I was given a HP 7200i CD-RW drive, and it's been
used as a CD-ROM drive because I've *never* gotten it to burn a CD
successfully.
The system I was using was originally Red Hat 5.2, upgraded to 6.0, then
6.1, now 6.1ish.. All along the way I've tried now and then, but the
drive always gets 50-70M in and blows up. Lots of sense data, retryable
commands, etc.. The original hardware was a VIA-503 mobo with K6-2/300.
I put the drive in my new workstation, a VIA-6100 mobo, PII 400, and
just put the old root disk in the new system so I never had to reinstall
or anything. The old system, now my server (the K6-2) got a fresh
intall of Red Hat 6.1, plus security fixes, some stuff added..
On a whim I put the CD Writer in the server, and it's written 7 or so
flawless CDs! It's the same hardware that failed before, so it has to
be something to do with my Red Hat install that I've used all along
previously.
Ever heard of this before? I'd prefer to have the CD Writer in the
workstation, but it's going good in the server for right now. I'm even
able to make a system backup, finally!

If you look, he is talking about an IDE system which is on the
second controller as slave! (I have scsi too and often pull drives
offline powered up! so your tip is of more help to me).
But let me try to answer his question here. If the drive is
not in use (ie: unmounted) pullling it out of the system powered up
(assuming he is using a hot swappable IDE drive rack) should not pose
a problem.
the key word for both IDE and SCSI is UNMOUNTED! if the
filesystem is in use one is asking for problems!

I believe Apple has set their imagewriters up as DTE equipment
instead of DCE equipment (common among Pcs) Therefore you will need a
full null-modem cable or plug to make it work (I have an Imagewriter
(the older Apple IIe one, never tested it). From trying to plug it
into a C64 Rs232 adaptor many years ago these things need a null modem
to work.
BTW my Digital LA-100 is the same way. plug a null modem into
it than the cable it works. On my Rainbow to use a standard serial PC
printer again the null-modem as it expects the printer to be a DTE
device.
As for the Mac serial question... You will just have to play
with it. Having a RS232 tester and a null modem along with the cables
would be a good start.
Speaking of the Imagewriter. what is the BPS, parity and stop
bits on it? I have no manual with my Imagewriter (the first unit).

Just read isapnp/pnpdump manpages and docs under /usr/lib/linux*/*pnp*
... (i dont remember the exact path, excuse me: better way "man -k pnp")
First try to solve problems with modem built-in serial "port" (those
docs explain the problem).
Perhaps you need to run some setserial lines during boot and system
initialization, then (when modem serial port is configured) and during
boot, you need an entry in /etc/isapnp.conf for your modem to work.
The "complete" problem is sumarized in the above docs.

Its being on COM5 only applies to MS-Windows. Do you have 4 serial
ports in
you system? Are you using them?
You didn't mention the model number of the modem or whether it was a PCI
modem. I will guess that it is PCI.
Currently, the easiest way to use a PCI modem is to down load the new
serial
driver from:
http://sourceforge.net/projects/serial/
Install it and reboot.
If you aren't using COM3 and COM4 disable them. If you don't have them,
see
what happens. In the unlikely event that you can't do anything about
this,
you will need to make "/dev/ttyS4".
If you want to make sure that the OS has found your modem, execute the
command: cat /proc/pci"

I think there's none, but an ancient obscure Diamond one. The most

3Com Homeconnect and the Efficient Speedstream [bar the 3010 model using

I guess you've been already adviced to consider an 'external modem',

it says that it is not able to be accessed. How do I get it to activate

Is this a PCI modem? Do you have a model number?
You can get some info at:
wysiwyg://57/http://lhd.zdnet.com/
If you have a PCI hardware modem, the best way to configure it is to down=
load
and install the new serial driver from:
wysiwyg://64/http://sourceforge.net/projects/serial/
If you have a PCI modem, you can see if the OS has found it by executing =
the
command: cat /proc/pci" or "/sbin/lspci -v"
After installing the serial driver, reboot the system.
