I've just realized that when I used Ctrl-Z at ANY time, I get an
|
||
unresponsive VC as a result. I have to go to another VC, and
|
||
kill the first VC. This problem is driving me nuts. Has anyone
|
||
had any similar experiences?

|

|

Just because your program is running does not mean that the code file
|
||
is still addressable under the name that you have in argv[0]. The argv
|
||
vector is simply that -- arguments. There is absolutely no requirement
|
||
that argv[0] even contain the name of the program. Several programs
|
||
even use it for an additional argument.
|
||
|
||
Let's face facts. UNIX is not MSDOS. You are not alone in the computer. An
|
||
other program running in the system may change the configuration information
|
||
which will make the data in argv[0] meaningless.
|
||
|
||
[BTW, this facility did not exist in MSDOS until 2.0. The file name is
|
||
not in the argument string. It is in a different area of memory --
|
||
tacked on to the end of the environment strings.]
|
||
|
||
>The UNIX shell can be modidied to pass the full path name into a program

|
||
|
||
No, I doubt that. Passing the full name will not crash any program of
|
||
which I am aware. The UNIX programs must be written to accept full
|
||
names as well as just their own name. It is totally legal and valid to
|
||
use "fred" as well as "./fred". One has a path, one does not. (They
|
||
may not be the same program however.)

|
||
|
||
It would seem to me that you would be better to place the configuration
|
||
file in a specific location, such as the /etc directory. Then, in that file,
|
||
put the file names to the data files.

Vue runs well if you have enough ram.
|
||
|
||
But for me olvwm is a MUCH nicer environment. Takes less ram,
|
||
more functionality for multiple workspaces. I.e. drag windows into
|
||
different workspaces, push windows offscreen into another desktop etc.
|
||
|
||
Olvwm gives you the multiple workspaces without getting in the way
|
||
or taking up to much memory.
|
||
|
||
Of course memory use because you have more workspaces is to be expected.

Actually, both of these so-called theoretical maximum compression ratios
|
||
are nothing but simple numbers the marketing types can remember. Both
|
||
MNP5 and V.42bis (which, btw, really is normally the better of the two)
|
||
are capable of *MUCH* higher than 2:1 or even 4:1.
|
||
|
||
I have some detailed specs somewhere, but of course, they're not in the
|
||
directory they should be in (and my copy of Recommendation V.42bis is at
|
||
work). Of course, the numbers don't really mean much unless the data is
|

basically designed to be highly compressible, but.... :-)

I have been looking around for a bootdisk to set up Linux on a System with
|
||
an Adaptec AHA 2842 SCSI-Adapter.
|
||
|
||
Recently I<>ve been told that one (still at the "interim-stage"?) is
|
||
available at:
|
||
|
||
sunsite.unc.edu:/pub/linux/kernel/images/boot284x.tar.gz
|
||
|
||
Did anyone succeed to set up Linux with this bootdisk yet?
|
||
|
||
Any information is appreciated.
|

|

Thanks in advance

Dan,
|
||
|
||
I understand your feelings, I had them several months back. However, I
|
||
didn't want to wait for Novell to fix it and did it myself. I've posted
|
||
my "How to make `man' work better" series here (c.u.u), but I'm always
|
||
willing to sent it to whomever needs it (the reason I'm following up
|
||
instead of replying).
|
||
|
||
The series helps you to set up your environment to find all the man
|
||
system pages, the Motif man pages (assumes you have the SDK), and create
|
||
a whatis database so the apropos and man -k commands work.
|
||
|
||
So, UW does provide it them, they just need a little tweaking. My comment
|
||
(about Linux man pages) was directed to the comments in the gcc man page
|
||
(about not bothering to keep them up to date) and the fact that some of my
|
||
commands *definitely* do not have a man page (or perhaps I retrieved an
|
||
incomplete Linux, but since 95+% of my commands have man pages, I suspect
|
||
they just weren't included in the release).
|
||
|
||
[ Note: follow-ups changed as this is becoming UW only. ]

What SCSI host adapter do you have? The Adaptec will remap the drive
|

to a drive with only 345 meg., 1 meg for every cylinder. Just curious,

and I still don't believe that LILO can load the kernel image from a

partition which spans beyond 1024 cylinders.

|
||
It's available under a number of guises. All of them require hacks or
|
||
extra hardware, or both.
|
||
|
||
You can get a patch (at munnari.oz.au, I believe) which adds Linux to
|
||
the list of supported CAP systems. It configures CAP to allow IPTalk
|
||
operation on a Linux system - you'd need a FastPath-4, -3, GatorBox, or
|
||
some similar IPtalk-to-EtherTalk router to handle protocol conversion.
|
||
|
||
I was able to install CAP on my Linux system using a hacked-up version
|
||
of UAR as the network interface. This UAR allows the CAP interfaces to
|
||
be bound to the "tnnl" DDP-in-IP tunneling interface. I also set up UAR
|
||
on my Sun SparcStation, acting as a router between the IP tunnel and
|
||
EtherTalk Phase 2. It's an ugly hack but it does work.
|
||
|
||
At least one group of people is working on adding native EtherTalk
|
||
support to Linux. They've got Phase 1 partially working.
|
||
|
||
Phase 2 (which is what most organizations are using these days) will be
|
||
a more difficult capability to implement. It requires a consistent
|
||
method of persuading the Ethernet interface to receive multicasts. A
|
||
fair number of the current Linux ethercard drivers do not yet support
|
||
multicasting, and [as far as I can tell] there is no consistent kernel
|
||
interface for registering with the network in order to receive arbitrary
|
||
packets (e.g. there's no equivalent to the Berkeley packet filter).

Well, over 12 years of empirical evidence show that the
|
||
bogoboost technique is safe and works fine. The 500 uS refresh
|
||
timer is close to optimal on most machines. The margin of safety
|
||
is considerable. You have achieved almost all of the boost
|
||
possible at that point. You need to go to much, much longer
|
||
delays before you experience parity errors: about 10000 or
|
||
20000 uS. But there is no point in pushing it to the threshold
|
||
because you gain almost no performance increase over 500 uS.
|
||
|
||
This technique is particularly well suited to older 386 motherboards.
|
||
Owners of this hardware may well want to take a look at Paul
|
||
Gortmaker's "dram" program and squeeze a bit more performance out of
|
||
their older hardware.

There is no need to swap the 1488 and 1489, as they have no relation to
|
||
the FIFO buffering. They are the drivers/receivers for the RS232 levels.
