What do you mean "will not recognize it"?
Try the following
/usr/sbin/chat -v "" AT OK "" </dev/ttyS0 >/dev/ttyS0
If it returns immediately, yo uhave found the modem on /dev/ttyS0
If it takes a while to return, you have not found it. Try /dev/ttyS1
instead.
If neither find it, then you have hardware problems. Is the modem
actually plugged in?

I'm not sure- it just has the title of the article in the box. (subject)
I assumed that when you open the article in a new window that it is already
downloaded to disk, in fact even viewing it in the preview pane I assume is
downloading the file.
As I mentioned I am able to save it after this initial failed attempt, but
this requires quite a few extra clicks if you as trying to save a large
number of articles, as a newbie like me must surely do.
Thanks for taking the time,
Robert

There are two editors mostly used, vi or emacs.
Both have more features than presumed from the UI,
but you can get most work done with only learning few of them.
The man page and the built-in help will helpful.
To start with vi:
vi testfile

Hi. I'm kinda new to linux. What window manager do you guys like best? I
like the GNOME desktop, but it seems kinda slow (slower than Windows 98). I
only have 32 megs of ram. I installed the WindowMaker rpm, and I tried have
GNOME use that instead of Sawfish, and it is faster, but It's still slower
than windows. I have Redhat 7.1. Also, On the login dialog, how can I add
Window Maker to the list of session types to start. Thanks in advance.

Any editor. Just remove the relevant line(s) or change them. Be careful
to honour the format. If you use /etc/shadow, also edit that file.
For both files, when programs need the info, they just read the files.
Ie, there is no cached storage of the contents. So you do not have to
worry about updating any such cache.

Content-Type: text/plain; charset=us-ascii

Hi All,
I've come across a slight problem, well, major problem and would like to
find out if anyone has come across this and knows a solution.
In a nutshell, my Linux system hangs under heavy disk I/O. The initial
problem I encountered was that my box hung up while compiling
glibc-2.2.3. I finally compiled it and it hung up again which running
the checks. This was not the first time my box died on me under heavy
load. In any case, my first thought was, LVM is acting up on me.
After I rebooted, I tarred up all data residing on LVM based
filesystems. I then created regular Linux partitions (83) on another
disk. The kernel I was running had LVM built in so I rebuilt the kernel
with LVM as a module. I rebooted again and created filesystems on the
newly created partitions.
I was using reiserfs on all the LVM based partitions and did the same
with the regular Linux partitions. I mounted the newly created
filesystems and started to untar all the data. My system hung up
again. OK, LVM was loaded as a module, so I rebooted, made sure that
LVM was not loaded, mounted the reiserfs fs and repeated the untar.
System hangs again.
Now I'm thinking, ok, it's reiserfs that causing the problem. After
rebooting, I reformatted the former reiserfs partitions, this time using
ext2 and mount them. lsmod shows no lvm or reiserfs, it's a plain Linux
system. I start the untar and system hangs again.
My system hangs under heavy disk I/O and I eliminated LVM and reiserfs
as the culprit. Could anyone help me get to the bottom of this? BTW,
Sysreq keys are useless.
My system:
Base System is RedHat 6.2
Kernel 2.4.4
Dual PIII600, 256M RAM
Adaptec UW SCSI
4 hdisks, CDROM, CDRW.
Thanks

Date: Mon, 28 May 2001 23:14:01 GMT
I just got FTP working and had a few more questions.
1. Now that I can FTP into my server I can see the following folders:
(bin, etc, lib, and pub). Am I supposed to be able to see inside all
four folders? I placed some text files into the pub folder just for
testing and I can see them just fine. While I CAN'T see anything in the
bin and etc folders I CAN see some files in the lib folder. Is that
okay?
2. How do I allow myself to be able to write to a folder?
Thanks for any help.

I assume that it's not reiserfs nor LVM, sounds like bad RAM,
compile a kernel if it stops with the message:
gcc caught fatal Signal 11
It should be RAM, take some out, if possible or/and try other and
compile again.

I'm still learning linux so I'm almost always loging in as root, and this message is
annoying cause
I have to press OK all the time. And because I heard you can change everything in
linux then I was
