That's probably because such a thing doesn't exist. An RS-232 com
port puts out a negative voltage for a mark and a positive voltage for
a space. The actual voltage depends on the hardware and nothing else.
There is no way to vary it with software. It is possible to toggle
the output of the handshaking lines, to give a pulse with a duration
controlled by software, but you cannot change the voltage.

As I recall, this one. Version 6.0.4 238 beta. It's on my SuSE 6.1 box
but it should work on the 2.2 box as well. We'll see -:)

More than likely.
Here's a general rule of thumb, so you won't have to say this sort of
subjective stuff. Your connect rate divided by 9, should be what your
download speeds are to a reliable server (like your home directory on
your ISP). Then you can really SAY linux is faster, if it is.
With PPP, TCP/IP and error correction accounting for the extra
overhead to set your pots modem's thruput to ~9 instead of 8 bits
/byte. You should see something like below for NON compressible zip or
TGZ files. Text files can do up to 4X with modem compression and up to
8X with software compression. In practice text files run about
2.0-2.5:1 compression ratio. So if your DTE is set to 115200 without
software compression, your transfers will be limited to about
11.5KB/sec.
----non compressible----rates with no ftp or net congestion.
40000=~4444 bytes /sec or ~267KB / minute or 3.7 minutes / megabyte
49333=~5481 bytes /sec or ~328KB / minute or 3.1 minutes / megabyte
50666=~5630 bytes /sec or ~337KB / minute or 3.0 minutes / megabyte
52000=~5777 bytes /sec or ~346KB / minute or 2.8 minutes / megabyte
Old Zmodem ASCII line transfers (phone to phone) are maybe 5% better
than above. Also, you can check your Sportster's latency to your DNS
server. It should be 95-110ms average, if you have a clean dns.
Let's see if this plays out in windows.
----first a non compressible file-------connected @49333 and confirmed

Do you mean a "Real player"or strictly mp3 player, like X11amp?
The real player works with linux but you have to download it and setup
the plug in's for Netscape.

I have both and 'generally' they can use the same binaries. However,
RH or mandrake is a different story

But when the syntax DEPENDS on it, it can be very difficult to trace a bug,
whereas it's relatively easy to trace matching brackets...

Nothing, but Occam is just a complete b'stard of a language and was a
perfect example of a bad way to do it...
People should be allowed a little freedom to indent in their own way, and
the bracket is, AFAIC a far more sensible way of parsing control structures
than counting spaces.

I need to use pppd with a odd speed of 64000 on a RS-232 serial interface,
but unfortunatly all that pppd gives is
pppd[546]: pppd 2.3.7 started by root, uid 0
pppd[546]: speed 64000 not supported
but the man pages for pppd mentions that on Systems like 4.4BSD and NetBSD
any speed can be specfied.......so IS LINUX ONE OF THEM ?
or is anyspeed on Linux is not supported with serial/ppp ?
if possible how can it be achnived ?

Subject: Bad magic number
Date: Sun, 29 Aug 1999 12:38:39 +0200
Hi,
i had problems mounting my partition /dev/hdb1 , so i ran e2fsck.
Here's what it put out:
> e2fsck /dev/hdb1
e2fsck 1.14, 9-Jan-1999 for EXT2 FS 0.5b, 95/08/09
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/hdb1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck -b 8193 <device>
I tryed:
> e2fsck -b 8193 /dev/hdb1
e2fsck 1.14, 9-Jan-1999 for EXT2 FS 0.5b, 95/08/09
e2fsck: Bad magic number in super-block while trying to open /dev/hdb1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck -b 8193 <device>
/dev/hdb1 actually IS an ext2 partition:
>fdisk -l
Disk /dev/hda: 255 heads, 63 sectors, 525 cylinders
Units = cylinders of 16065 * 512 bytes

/dev/hda1 * 1 261 2096451 6 FAT16
/dev/hda2 262 509 1992060 83 Linux
/dev/hda3 510 525 128520 82 Linux swap
Disk /dev/hdb: 32 heads, 63 sectors, 823 cylinders
Units = cylinders of 2016 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hdb1 1 823 829583+ 83 Linux
I created /dev/hdb1 yesterday with fdisk, formatted it with YaST,
mounted it on /ext and used it to store one big file (about 400MB).
Everything worked fine. Finally i did shut down my system the normal way
without problems. When I tryed to mount it that morning, there was that
mess.
How can i get that fixed ?
Thanks for your help in advance,
Martin

As you have probably already seen, there is more than one way to skin a
cat. I use RH6 too, and I believe I have a relatively painless way to
accomplish this.
Copy the file /etc/X11/xinit/Xclients to ~/.Xclients
Now edit that file. In the top 5 lines, you will see
PREFERRED=
Give that the value of the manager you want.
ex. PREFERRED=AfterStep
See if you have the file ~/.wm_style
If not, create one with "AfterStep" (minux the quotes) as its only content
Good luck!
