You don't have a modem. The man who sold you the thing you call a
modem is either deluded, a liar, or did not understand what you

Get a modem.

Does anyone have an idea of what is wrong ? Is this a bug in the kernel,
or perhaps I need to upgrade some programs ?
BTW, I tried upgrading to 2.2.8 but this gave me a LOT more problems. Is
2.2.9 now considered as safe ?

Are you sure there isn't an /etc/securetty file lying around on the
floppy? This could prevent logging in as root as well... see man login

almost certainly (I don't have it here) has pointers to

For example IRQ 13 is a fast IRQ handler that does not obtain the locks,
and cannot cause a reschedule,
but IRQ 16 is a slow IRQ handler that must aquire the kernel spinlocks
and can cause a reschedule.

Humm... I guess I'll have to upgrade my 2.0.31 kernel on my black box

I don't understand. Doesn't an incompatible new version of a library
come out with a different soname? Why can't you have multiple versions
of the library? You're wasting a bit of disk and memory, but that's all.
RPM should have an option (probably on by default) to not completely
delete a package that provides a library that is still referenced when
doing an update with a newer version of that package, unless the new
package replaces the same version of the library.
The dynamic loader could also be smarter (perhaps it is in the latest
release, I'm still using 2.0). If the specified library version isn't
available, attempt to load a newer one (with the same major version
number). Of course, you can get a similar effect just by creating a
symbolic link for the non-existent libraries.

hi,
I stayed with 5.2 and upgraded through the 2.2 kernels to 2.3. The
RedHat web page has instructions on upgrading to 2.2.x which work fine.
I don't intend to upgrade to RH 6.0 because I use gnat and don't want
to get into the c library war crossfire.

Well, at least with RedHat's Manhattan version of glibc 2.0.7 release
19 for the Alpha, it creates it as libc.so.6.1...I'm not sure why it
is different for the Alpha, as the same release for Intel is simply
libc.so.6, as you say.
Didn't RedHat have to use glibc for the Alpha release, and wouldn't that
have caused them major headaches to be trying to support patch sets for
only Alpha to fix things to work with glibc? I can see that as one good
reason to have switched to glibc even if it wasn't stable.

I saw your post on c.o.l.dev.sys ("Glibc rant") and I hope you don't
mind this unsolicited mail...
I have RH5.2 at home, v. old slackware+RH5.2+debian (glibc2.0) at work,
and have fear in upgrading to RH6. I'd like kernel 2.2 (which RH6
doesn't have yet) because it looks like ufs will be homing in on that
one, and we have CDRWs.
But I can't actually find any changes list or faqs about 2.1 probs!
I've got a few quite old bin RPMs from RH5.2 contributors: xview (sorry
8-), hugs and the glasgow haskell compiler to name but a few, and
although source rebuilds would be possible, it would be a damn waste of
time. Do you know how to find out what breaks and why? You mention
XEmacs (part of powertools, so I suppose some RPMer will fix it pretty
soon if not already) and egcs (which we use already): i'm guessing
you're talking about template probs with the latter?
Any info/comments you have would be most helpful 8-)
Thanks,
Nick/

Hi everybody:
Need some help...
I've got to develope a script a bit difficult. (at least for me).

The file is sorted by frequencies. I guess that I must use commands like tr,

Please some help...I've been investigating for a week and I'm getting mad.
Thanks in advance.

My attempts to initialize using normal assignments don't seem to work. I'm
more and more convinced that there are significant* changes in signal handling
between 2.2.1 and 2.2.9 (probably at 2.2.5).
Programs that don't work under 2.2.9 work when rebooted back to 2.2.1
What was changed?
*significant--affecting ME (or anyone else, since this is a production
release).

No, 256 could be a correct answer, though 8-bit ASCII is properly called
Extended ASCII. It is charset ISO Latin-1. It is 8 bits wide, with the
extra
characters used for non-english letters.

In traditional ASCII (the 7-bit version) there are. See above.

The charecter `C' with a squiggle under it: (�).
A quick web search on Extended ASCII turned up this decent looking page:
