Well, I'm not a compression expert, so don't know what you mean.  -lh1- looks
like an lharc type.  The compression ar uses is lzw as described in ACM and
implemented in Unix compress.  It doesn't add Huffman on top or any of the
sorts of things recent lha or zoo do.  Nor will it ever.  There isn't enough
room on an 09.  For OSK, I usually use zoo anyway.  Lharc can be faster but
does not seem to be very portable or even compatible with itself.

Thanks for reading...
I need help on OS9 interprocess communication (ipc) features for my servo
control and acquistion application. I've been given a project of porting over
Versados 68000 code (c, fortran, assy). This code generally uses TRAP calls for
ipc including wake-ups and message queues. My task is to rewrite the code in C
using events,  semaphores, traps, signals,  or whatever appropriate in the
transcription. I have P. Dibble's Insights book but there is no OPC (other
people's code) to use as an end to end working guideline. Is there any
downloadable or textbook source code available that would be helpful?
Thanks in advance for any leads or advice. Glen/Fort Worth TX

I installed the GShell32 patches to GShell -- wow, Multivue has never been so
nice!  I've been running it for two days now without a crash, plus running StG
BBS, and opening windows like mad....

I did have to manually patch the new GShell to use the new GRFDRV for faster
PUTs on an 80x24 screen.  My two questions:

(1) Where do I patch GShell to obtain similar speeds on the 320x192 screen? (2)
Kent Meyers told me once that he had patched GShell so that icons on
    an 80x24 window would be twice as wide, thus preserving the proportional
    size of the icon (icons on 80x24 screens look narrow as apposed to 40x24)
    Does anyone have this patch and would share it?/

Kevin,

I havn't worked it out yet.  But it is true, there is a recursive process going
on here.  There IS a CLOSE to the path, which we have pretty much determined is
the printer (since we believe we do not get the error if we are writing to a
file).

It's a puzzle!

By the by... just set up a FHL KiX-30 (a/k/a Hazelwood EK-30).  It's a real
screamer compared to the old Uniquad-20 with 12 users!  Are there other users
on this board?

Final thought... where is the un-archive utility in the CIS library for files
with the .AR extension.  I know there is a specific version to be used by this
forum now.  Can't seem to find which LIb it's in.

Tnx for the repy, and sorry to take so long to respond.  I can't believe it has
been over a month since I had been on!

Happy tax day!  <g>

Sounds like something in the linker.  Let me give you an example.  I have a
library function that issues a BREAK on the modem port.  This is the code:

 send_break()
 {
        if (_ss_sbreak(mp) < 0)

 #asm

 I$SetStt        equ             $008E                   ; 8f is get

 _ss_sbreak:
                link    a5,#0
                movem.l D1/D2/A0,-(A7)
                move.l  D1,D2
                move.w  #SS_Break,D1
                os9     I$SetStt
                bra     _sysret

 }

Notice the bra _sysret call.  Sysret is located in the sys.l library. If the
program is very large, over 32K, and the location of the break function is at
the beginning, when I link in  sys.l, I will get an error if the location of
_sysret is greater than 32K from where it was called.  I am not good enough at
OSK assembler to fix this problem. So for now, I just make sure I put the break
function at the end of the program source file, and then link sys.l first (if I
can).

I belive you might be having the same trouble.  Perhaps someone else here can
shed some more light on these problems.

Mark,
   That sounds like what I ran into.  When looking at the assemble code
generated, the error was pointing at the second statement in the program.

P_id - getpid();

Wpath2 = open("/w", 3);     <-- This is where the error came in

 The code was:
   moveq.l #3,d1 :2

   lea_64(pc),a0   <-- Here is the VALUE OUT OF RANGE ERROR    move.l a0,d0 :2
   bsr open

 The only other possibility I could think of was the fact that Wpath2 would be
the last variable name, if the names were sorted, and it for some reason was
out of range when linking. I think I will be running into the error again as I
add more to the program, and if I do, I will try renaming the variable, and see
if the error transfers to the new last in line variable.

This is very strange.  I don't see any reason for the compiler to put out code
like this.  How is Wpath2 defined?

This IS the problem, assuming that _64 is the label of the "/w" constant, since
the compiler always puts string constants at the end of the module.

I guess that his program then is much larger than 32K, so the string constants
can't be reached.  Perhaps he can fix this by defining the constants as a
variable?  Strange I never ran into this, but then the largest program I've
done is Sterm and it is only 54K.

Larry,

This is the problem, and it has nothing to do with variables. If you look
toward the end of the assembler code, I think you will find that _64 is the
label of the "/w" constant. This instruction puts the address of that constant
in a0. The problem is that the compiler puts all string constants (like "/w")
at the end of the module, there is no way to get around this (that I know of)
other than make the modules smaller. As soon as you add more code, it will push
the constants beyond the 64K limit, and this will happen again.

I strongly suggest that you take the time now to learn how to use the linker
and make. It will actually save you time, as you won't be compiling one large
module each time you make a change. I'd be happy to provide some sample make
files, and there are pleny of people around to help out. Once you learn how to
use make, and the linker, you will never go back :-)

   It definently sounds like that is the problem. When I went through and did
some cleanup and pared the program down some, the error went away.
   It looks like I will have to dig into using the linker. Its funny but I had
no problem using the RMA assembler and linker on the CoCo, but I can't get a
handle on the linker for C.  But I will try...

   So individual modules can't be greater than 64k, but you can link any number
of 64k modules together(within system limits) ?

  Thanks Bill

Mark,

The 68000 can only have bra and bsr in a 32K max offset (the 68020, etc) can
manage a 32bit offset). The linker is supposed to generate an entry in a jump
table for branches out of reach. A bra.w is converted to a jmp by the linker.
Could be that since you have coded the routine in asm that the linker is
missing the call?

Bob,
  The routine was written in C, not asm. In the process of compiling the
program, during the r68 pass, a **  value out of range ** error popped up.
  The error was reported as such:

Value out of range

lea_64(pc),a0
            ^

  So I recompiledthe file using the -a option, in order to see the asm code
that was generated and where the error was. That short bit of asm code, is what
was produced by the compiler.

Just thinking out loud...I wonder if the assembler/linker can handle calls past
+/- 32K only if the dest. is in another file? If the problem comes up during
the assembly then the assembler will report the branch error. If it just sticks
in a label for the linker to worry about, the linker will create the jump
table. Seems to be one more reason for breaking up programs into smaller
segments.

  The only problem I have now is that When I started writing this program I had

That sounds like a reasonable guess.  In any case, in my example, it is not
possible to do that (make it a jmp) and still have it work correctly. Perhaps
someone else can come up with a better solution.

I've been wasting a bit of my time looking at disasms of some of the mm/1

example, I see stuff like:

Which, I know, means to move a byte from $9ffc01 to register d0. However, are
not all the ports addressed at EVEN memory addresses? Don't know why I figure
that...I just figured it.

So, assuming that there is a device with its base addresses at $9ffc00, just
what is at $9ffc01? BTW, the mm/1 tech man suggests that the MC68901 on the
main board is at $9ffc00.

I must be missing some important hardware concept!

That address is where the 68901 on the mother (CPU) board is.  The base address
is indeed $9FFC00 and the offset of 1 points to the general purpose data

Hello Bob

The reason why you use 'odd'-addresses and not 'even'addresses is the way the
68000 cpu is connected to the DATA-BUS. If you use move.w $10000,d0, bit d15-d8
will be read from $10000 and d7-d0 will be read from $10001, so if you only
read a byte from an I/O-chip like MC68901, which is an 8-bit device, you need
to access it via 'odd'-addresses, otherwise you are likely to get an
'error-102' or 'garbage'. If you need to access several register in 'one go',
you can use the MOVEP.L instruction. It will read/write 4-bytes on every
second-address from base-address. Example:

MOVEP.L d0,$ffa001 will write 1 byte at $ffa001 and 1 at $ffa003 and 1 at
$ffa005 and one at $ffa007.

I've been setting up my system to use login, instead of just booting with a
startup file. I have got tsmon running from startup to monitor the terminal
posts. This works fine. However, I would like to force anyone just turning on
the computer to go though login as well. I can do this by sticking a login
command in the startup file...however, everything past the command gets
ignored. Since, I want to set up some extra windows...this is not good. I can't
set the windows first; that would eliminate the security of login. Seems that I
am in a catch-22 situation.

Next, I figured that I'd give each user his own directory. And to make it hard
for other users to examine the files of others I also figured I'd set the
access permissions of the directories to prevent public read/write. No good.
The first thing login does is try to chd to the directory. But, if the
directory does NOT have public read/write then it can't do so. Frankly, this
doesn't make sense to me since login is running in superuser mode. Is there a
way around this one?

processed). However, if I just set owner permissions in "steve" then motd is
displayed -- but I then get the message "login: can't chd to /dd/usr/steve".

I don't know if this is significant, (no manuals), but give it a try and see
what happens.

Hello Bob

The best solution for your first problem is to make a 'new' sysgo, which does
not 'fork' shell after execution of 'startup', but instead fork 'tsmon' on your
'console' or just 'login' on your 'console'.

Your second problem is related to 'ALWAYS WANT TO BE SUPERUSER'. NON-superuser
users will have normal protection between access to other users files.

I hope someone here (or at Microware) can be of some help.  I have a client
that has two GESPAC 68030 based OS-9 systems that are running on an ethernet
network.  They appear to be using sockman, ifman, inet, tcp,, udp and the like
with file dates from around 10/90 to 11/91.  They are not attempting to connect
the systems to a PC running Windows and the TCP/IP package from Distinct
Software.

Unfortunately, they are not having a lot of success.  They apparently cannot
locate the internet address for their OS-9 systems, nor can they get any of
Distinct's utilities to be of help.  For the most part, they know little to
nothing about their OS-9 system, and the original vendor is no longer
available/or interested.

Can anybody suggest a course of action to get their PCs talking to their OS-9
system using TCP/IP and FTP?

Thanks,

The internet addresses are usually in /dd/inet/etc/hosts...

Any HP Laser Jet experts out there? I just got an Epson Laser printer and am
trying to learn the PCL language...it's never as easy as it seems. I have the
Epson "manual" and a couple of books on the subject. I was trying to set the
page size and got real confused, real fast. The Epson manual just lists the
sizes available for the "ESC & l # A" command--it doesn't bother to list the
values needed for the different sizes. However, I have a book on the PCL
language (The Laserjet Handbook, Bennett & Randall, Brady) and it does list
them. For example, the book clearly states that a parameter of "6" will select
Commercial 10 (envelope) size. Of course, this doesn't work (If all this
worked, then what would we need CIS for...hmmm, is there a conspiracy?). I
grabbed a few programs for lasers off the UNIX forum...and one one of them sets
the printer properly....but it uses a param of "81" for C10 env. This program
has a few other values...but it is not complete. I started just sending test
values out to the printer...but having to constantly turn the sucker off line
and then wade through the "easy to use" panel display gets real old, real fast.
So, either I'm missing the logic of sending a "81" when a "6" is called for (I
fail to see the relationship), or the book I have is lying, or... Anyone happen
to have a table of sizes and params. This is not a big deal in itself...but I
have  the feeling if I can't even set the paper size from the computer, I'm
going to have even more frustrations when it comes to other goodies.
