I've heard of OS9 over the years and now I'm using Phillips DVI machines which
|
|
use it. Can someone give me the basics about this opperating system? It it
|
|
similar or derived from UNIX?

Hi Andy,
|
|
|
|
There's a file called OS9FAQ.TXT in Library 1 you can look at.
|
|
|
|
Philips CD-i players also use OS-9, as do many of the coming interactive
|
|
settop TV boxes. It's also heavily used in industrial controllers, such as
|
|
factory line supervision, suspension bridge monitoring, and even Disney rides.
|
|
|
|
It's native file system and many of its path operations seem to be derived from
|
|
Unix, but the OS itself really isn't. When it first came out about 16 years
|
|
ago it already had much of what is considered "new" today... microkernel,
|
|
loadable device drivers, modularity, ROMmability, etc.
|
|
|
|
Ask away if you have more questions.
|

Dear Mike Ward,
|
|
|
|
unfortunately I did now overwrite the OS9MAX update for OS-9 CD-ROM creating
|
|
(the file name was OS9MAXIM.ARJ) Can you re-contruct the file with description
|
|
or must I upload this again.
|
|
|
|
Do I have to fill in the item hostname ? What is it for ?
|
|
|
|
Thanks

There is a spreadsheet for OS-9 available from a company called RTware. It's a
|
|
threedimensional spreadsheet, has much more functions than a regular
|
|
spreadsheet. It'S so versatile, it can be used as an integrated programming
|
|
environment to create realtime applications e.g. for control systems.
|
|
|
|
It's called ControlCalc. To get more info about it, you may want to contact
|
|
Rich Clarke at RTware. Their email address is: rtware@mercury.interpath.com

Sb: #Checking on dead parents
|
|
Fm: Bob van der Poel 76510,2203

To: All
|
|
|
|
Is there any way a child process running in user mode can generate a signal if
|
|
its parent dies. Here is my situation:
|
|
|
|
parent processes spans child,
|
|
parent/child communicate though shared data module created by parent,
|
|
parent/child sync via events (event created by parent).
|
|
|
|
If the parent dies a sudden death, the child not only hangs around forever, but
|
|
even if you kill the child, the data module and the event still hang around. It
|
|
would be nice if the child could be notified if the parent dies...then it could
|
|
delete the data module (if it still exists) and delete the event.
|
|
|
|
Any ideas on this appreciated!

Bob,

|
|
>> It would be nice if the child could be notified if the parent dies <<
|
|
|
|
Since you say 'if the parent dies a sudden death' I guess you can't signal the
|
|
child from the parent, since the death is unexpected. You could have the child
|
|
check that the parent is still there, however.
|
|
|
|
It's a while since I did this, so you might need to improvise a little. Try
|
|
having the parent pass the child the parent process id. At regular intervals,
|
|
the child then fetches the parents process descriptor using _os_gprdsc(). If
|
|
the parent is dead I THINK you should get an error from that call.
|
|
|
|
I used to do a similar thing when I had problems with a process locking up on
|
|
I/O. From the process descriptor (if I remember correctly) you can get the info
|
|
normally shown by the 'procs' utility, so you can tell if all I/O activity on a
|
|
process has halted, or if it's not taking any CPU time.
|
|
|
|
Hope this helps.

Has anyone ported a ppp (point to point protocol) interface to osk?
|
|
|
|
I have seen source code for a unix implementation of ppp and it doesn't seem to
|
|
be all that complicated...but the unix code I saw created device drivers to do
|
|
this. I'm not really knowledgeable about internet protocols, or unix device
|
|
drivers to even start a port of this.
|
|
|
|
It seems that my internet provider will no longer be supplying shell accounts
|
|
and ppp will be the only access. I don't really need all the gfx stuff
|
|
available under windows...so can this be done?

It looks like a pretty big undertaking. I believe I saw where someone said
|
|
they might put a bug in your ear <G>
|
|
|
|
I have a zip file containing all the standards for all the protocols. The zip
|
|
is about 833+ K Would you like for me to email it to you?

|

|
|
It certainly can be done, but whether anyone or group would have the time to do
|
|
so is the big question. It is one thing I would have liked to have seen on our
|
|
systems, but after taking a look at it, it looks like a tremendous amount of
|
|
work ahead.
|
|
|
|
As a matter of fact, just last night I installed Winsock and Eudora on my
|
|
brother's PC just to see if I could and to become familiar with it. I set it up
|
|
for my own account, (None of us have figured out how to come up with a complete
|
|
logon script yet - if possible) and I don't think anyone could figure out the
|
|
contortions we have to go through to get on <G>
|
|
|
|
Anyway, I went in with Eudora and got my mail, I think I had about 4 msgs. It
|
|
was fantastic. In fact, I happened to have a MIME- encoded file attached and
|
|
it came through automatically. Much simpler than using my system. It's not
|
|
that bad with a shell account, but with the rates we are getting blistered
|
|
with, you can't afford to spend so much time online reading and replying to
|
|
mail.
|
|
|
|
I've just about decided it's easier to switch than fight where Internet access
|
|
is concerned.
