Just to confirm, we are running a dial-in Bulletin Board under sysVr4.2 and

we get endless complaints about sz. It's even worse when they upload to us.

So it's not specifically a Linux problem. We too have tried changing packet

separate 16550s with equal problems.

Our drealmBBS system should be in general distribution very soon now. It's
|
|
got quite extensive configuration options, and the menus are what I would call
|

semi-programmable. Trouble is as yet you have to edit them by hand (we
|
|
haven't had time to write fancy menu creators).
|
|
|
|
We are expecting a load of flames from this group, as we are not distributing
|
|
source with the general release, but we have been careful to not infringe any
|
|
Free Software licences (I hope people will point out if they think we might
|
|
have slipped up somewhere!)
|
|
|
|
The two-node version will be free, but we'll ask for some nominal registration
|
|
fee for a higher-node version - on the assumption that if you can afford more
|
|
than one line and modem you can afford to help us with some of our costs (as
|
|
yet we have *still* to break even on our own system after 4 years!!!)
|
|
|
|
It's got things like top callers, message posters and message/call ratio and
|
|
we intend to add more as time goes by.
|
|
|
|
We also commissioned an offline reader which runs under windows and is now
|
|
available as Shareware. There is an alternative OLR which is available as
|
|
source for unix and dos. I can give out details but I had better check with
|
|
these guys that they are ready to be 'advertised' here (-:
|
|
|
|
While designing the system, we bore in mind what was popular about the DOS bbs
|
|
systems, (including definable user flags and security levels), while trying to
|
|
also provide an interface to the normal life of a unix system (for instance
|
|
you can import Unix mail into internal drealm format and out again).
|
|
|
|
Please don't mail me to get a copy yet, as I will certainly announce the
|
|
release in various places in the near future.

Hello:

Does anyone know whether it is possible to access a stacked drive

Hi,
|

has anybody used the Hayes comms accelerator with Linux, and does
|
|
Linux support it ? reading the blurb on the side of the box
|
|
yesterday, it say its a 16550 COMPATIBLE board that is capable
|
|
of support 115200 data rates.
|
|
|
|
Its also billed as a windows 3 comms accelerator.
|
|

Thoughts anybody ?

Even DOS and Windoze require administration. It doesn't get done, and that's
|
|
why most DOS/Windoze machines are a MESS. Stray files, improperly configured

software, lost temporary files taking up disk space. What a waste of money

That's hard to say... I heard that OS/2 is a pretty huge operating
|
|
system (yeah, like Linux isn't :), so I can only speculate on how much you
|
|
can alter Drive 0. If you must keep a lot of DOS stuff installed, you'll
|
|
probably need to leave that drive alone.
|
|
|
|
Drive 1 should be 100% Linux, though... But even that much space
|
|
won't be enough for a really good system. If you have 8 megs of RAM, you'll
|
|
probably want to have at least a 5 meg swap partition (that's what I have,
|
|
and so far it's worked pretty well); if you have less than 8 megs of RAM
|
|
you'll need a bigger swap partition. Also, for future upgrading purposes,
|
|
you'll want a separate root partition (I haven't set one of these up myself
|
|
yet, but I would imagine that 5 megs would be pretty good). Soooo...
|
|
|
|
That would make Drive 1 split as such:
|
|
|
|
5 meg swap partition
|
|
5 meg root partition
|
|
90 meg Linux partition
|
|
|
|
With that setup, you'll probably be able to squeeze in the Linux
|
|
source tree (essential), gcc (essential, but the debugger stuff and
|
|
translators can be skipped if you want), and possibly even a decent
|
|
X-Windows setup with TeX, Ghostscript, and most of the other frilly things
|
|
that make X-Windows as way-cool as it should be. That won't leave much open
|
|
space, though; I'd recommend losing some of the DOS partition on Drive 0
|
|
(perhaps put the root and swap partitions there... Better yet, lose DOS
|
|
altogether and make that a Linux drive... :).
|
|
|
|
That's about it for me. I'm sure some people would argue that the
|
|
above isn't a good split, but to each his/her own.

|
|
|

I am right now doing a test with 5 xterm open, running nn, vi, joe, dos and

top. And dos is running MicroEmacs for dos. I also have the xfm-1.3 file

So, I am happily writing this article in an xterm. Try something similar in
|
|
OS/2. I used to have it installed, but 8MB is barely the minimum, and when it
|
|
starts swapping, it seems as if it will never end. Linux, on the other hand,
|
|
just swaps a little when I move to another window, but it's just a few seconds.

Subject: 56.6 Kb simulated with 2 28.8Kb modems. Is it possible?
|
|
Date: 23 Sep 1994 04:00:08 -0400
|
|
|
|
I just had this idea. There must be a way to simulate a 56.6 Kb connection
|
|
without the need unconventional equipment (from the home user point of view,
|
|
I mean). May be with just 2 28.8 modems connected to 2 regular phone lines and
|
|
some smart low level packet routing ( choosing for a packet the least busy
|
|
line) it has to be possible. It will be way much cheaper than the special
|
|
56.6 circuits, and it could even encourage the vendors of those equipments to
|
|
lower the price, given the cheap alternative.
|
|
So, whats your opinion. It has to be possible. Writing a whole operating
|
|
system was much more difficult and it has been accomplished. This is just a
|
|
small retouch.

Only if you have a posting that is not more appropriate for one of the other

BTW the ethernet is $70 I believe.

Subject: monitor ptrace process & read from pipe or socket
|
|
Date: Sat, 24 Sep 94 11:59:01 GMT
|
|
|
|
To monitor a ptrace'd process, I must use wait() on it. To manage
|
|
the user interface of my program, I must monitor pipes and sockets.
|
|
I do that with "select". Is it possible to do a select that
|
|
will terminate when there is something available (being
|
|
sure that wait() won't block.
|
|
|
|
Currently I manage to achieve this using two processes. The main
|
|
one do wait(), and the child do select. Whenever the select
|
|
return something useful, the child send a signal to the parent,
|
|
effectivly terminating the wait(). The parent then read the different
|
|
pipe and socket and send a signal to the child so it can resume
|
|
select().
|
|
|
|
Is it possible to do this with a single process ?
|
|
|
|
==============================================================
|
|
I am including a small information on my project in any case.
|
|
|
|
I am building a debugger for linux (GUI). This debugger
|
|
unlike most, do not rely on getting all its
|
|
symbolic information from the executable file. Instead it rely on it
|
|
only for getting a basic map of the different modules composing
|
|
the program. When information is needed on a specific module, its
|
|
corresponding source file and object file are located and
|
|
information is then read from there.
|
|
|
|
Why one would do this ? General performance!
|
|
|
|
The executable file is made with "partly" stripped library (strip -S).
|
|
|
|
So it is smaller and link faster.
|
|
lib file are also smaller (not a duplication of all
|
|
the full object files content), again help link faster.
|
|
|
|
load faster: Only the basic map of the exe must be read.
|
|
|
|
Use less memory: Only the module which are effectivly traced
|
|
need to be load in memory.
|
|
|
|
To give you an idea. The program I usually work on is 2.5 megs
|
|
large. The executable file with basic symbolic info is 3.2 megs large.
|
|
If linked with all symbolic info, it goes to 15-20 megs. No way one
|
|
will debugged this using a standard debugger on a 16 megs ram machine.
|
|
Even if you have the ram, the general performance of a debugger is
|
|
weak (slow). It requiere somewhere around 32 megs of swap to operate.
|
|
|
|
With my debugger, it used around 1.5 megs of ram to operate and it let
|
|
me debugged anywhere in the program without restriction.
|
|
|
|
Anyway, this is my project!

Easy: because I write my thesis faster with emacs and LaTeX than with MS-Word
|
|
or whatever you may think of.
|
|
|
|
I have written my diploma thesis with LaTeX and am going to write my PhD
|
|
thesis with LaTeX as well. Having seen lots of colleagues fiddling with
|
|
Word or WfW I never would want to change :-)
|
|
|
|
FYI, LaTeX as well as Emacs are probably better tested than any of the
|
|
commercial packages, because the source is available, so, if an error
|
|
occurs, a capable person can trace it down and send a bugfix or at least
|
|
a detailed bug report to the maintainer. As far as I can remember, the
|
|
2.* TeX package is almost bug-free (Don Knuth offered a price to anybody
|
|
who could track down a bug in TeX); I am not sure if this is also true
|
|
of the new TeX 3.* versions.
|
|
|
|
Sorry, I had to get this off my chest.
