Is there a list of the very informative error message the Mac
sometimes hands out?

For example when using MS word - the application will quit and
the message   application suddenly quite type 2 error.


       Looking in the system manual that came with our Si - it
mentions to make a note of the error number - but I can not find
a listing of them.


Is there a complete list?

    I use the commercial utility LapLinkMac (Travelling Software)
to set up a 115200 baud link from a Mac Plus to a PC clone, so it is
possible to exceed the normal Mac limits without using AppleTalk.  The
quality of the transfer is very good.  Perhaps you might buy a copy
and ask their tech support how it's done.

    I suspect that the PC side of LLM involves reprogramming the
UART or some similar low level trickery because the PC is not
necessarially restored to its default state after a transfer.  Perhaps
LLM on the Mac side reprograms the Zilog SCC?  The later Mac models
may have different low level feature access protocol because of
greater VLSI and ASIC usage.

    The very early (1984) hard drives were accessed via a serial
port and I think that they also ran faster than 57600 baud.

The standard serial drivers will go up to 57K baud.

I find it very irritating that alert notifications still are
"owned" by the foreground application. This means that the
foreground application STOPS...

It does not make me happy when I find that the number crunching
application I left in the foreground over the weekend stopped
at Friday 6.00 PM because I got a notification alert from somewhere.

Irony Alert!
I suppose I should be happy that the foreground application was not
controlling a chemical plant or a heart-lung machine at a hospital.
I guess that such things should be done on a PC instead.
End irony alert!

I fully agree!  I use PopMail II, and this is my major complaint.  I
just wish that people would use the "flashing icon" style alert (when
the icon in the menubar starts flashing, then you know you should go
and do something about it -- it doesn't stop the top process!

I have had an overnight backup stopped right after I left, because I
forgot to quit PopMail and some new mail arrived.

I really shouldn't have an application stopped -- even a background
application, but especially not the foreground one -- just because
somebody wants to tell me something!

I too find this especially annoying.  But I dont think that it is the
Notification Managers fault.  I place the blame on the applications.
The Notification Manager provides three types of notification that are
easily changed from within the application.  It is a simple matter
to provide preferences for the notification.  If you dont mind the
alerts (which I dispise) then you could use those.  You can also use
"Polite notification" (the flashing icon).

Applications need to use the features that are available and give
users access to set them the way that they like.

Any conformant application written according to the rules
lets you set the notification level you want; diamond,
diamond&icon, or diamond,icon and alert.

If it doesn't, it's just as bad as software locking

Yes, thats is all very well. However, it is not enough.
I don't want to check that every notification alert in
every application, control panel, etc. is turned off
before I start an important and time-consuming job.
And how do I know I found them all?

Our department has built a peptide-synthesis machine that is
controlled by a Macintosh Plus. If that computer stopped because
of a notification alert then it could cost us thousands of dollars.
Currently we use System Software version 3.2 to be safe from any
unwanted notification alerts.

I run molecular mechanics programs (MM2(91) and MM3) and I also use
semiempirical quantum mechanics (MOPAC) on my Macintosh IIfx.
These programs are takes many hours or days to complete and they are
always in danger of being stopped by a notification alert.
I usually remember to turn off notification alerts in MacPost
and to put the Finder in front before I leave for home...

Ah, but then the default should be level 2 (i.e. icon and diamond)

If you REALLY want to, why not patch NmInstall to remove any alert
strings it might have attached ? :-)

Yes I agree. To use the Macintosh for scientific calculations or
as a controller for instruments I will have to patch NmInstall.
Maybe Apple will write a new TN on this subject. ;-)

Eudora allows you to specify that they go away after a certain amount of
time.

I agree with the original point; the Notification Manager is EXTREMELY
obnoxious.  No doubt this is so that it can survive whatever screwy state
the frontmost application might be in, and still do its job.  However, it
sure would be nice if something could be done about it.

Fear not brave soldiers! My Control Panel for doing this is just about
ready for release. It will take those nasty notifies with strings,
and copy the strings into the Control Panel's list, then just do the
icon and mark (i.e. removes the string)!

And there will be much rejoicing!!!!!!!!!!!!!!!!

Do you know if it would be able to deal with AppleShare volumes going
away?  Or spurious DiskInit alerts?

A real obnoxious problem that I have been having with uAccess (though
by no means the fault of uAccess) is when I leave for the night, my
file server often decides to go away, bringing up an alert that seems
to stop the Mac, or (if I forget to put a disk in the CD Drive), I
get an alert asking me if I want to initialize the disk in the CD
drive.

It's one of the Process Manager's code segements.  The Process Manager is
actually an application.  It has all of the normal things a standard app
would have including the code segments, a jump table, QuickDraw globals,
A5 globals, etc.  All of the code segments have been given a special type,
'scod'.  You'll even notice patches to GetResource that will replace 'CODE'
with 'scod' to allow the LoadSeg trap to work with the Process Manager's code.

Subject: Notification color icons
Organization: Computer Science Dep. - Milan University
Date: Wed, 8 Apr 1992 11:48:27 GMT

I have a small application that can work in background to process
apple events, and sometimes needs to interact with the user.
If it's in the bg, it posts a polite notification request by calling
AEInteractWithUser with a NIL parameter.  IM 6 says this will default
to a standard behavior.  Yet, what I get is a flashing SICN in the
menubar (the SICN resource has the same ID as the ID of the application's
icon family).  I would like to get a color icon (i.e. ics8 or ics4) used
instead, at least on a color screen.
  Now: IM 6 says I should put in the nmIcon field of a NM request record
  a *HANDLE TO AN ICON FAMILY*.  What does this mean exactly?
  Should I pass a handle to an ics8 resource, for example?
  How could the Notification Manager tell a handle to a SICN from a
  handle to a resource of a different kind?

  Thanx in advance for any hints on this issue.

    An IconFamily, is an "as yet undocumented" data structure which is

System 7 that the Finder, Chooser, Notification Manager, etc. use to draw

    MacDTS is preparing (has already released??) a Tech Note which

includes the info for creating & disposing IconFamilies.

Here's what I've reverse engineered:
An icon family handle is a handle to an array of 10 handles, each of which contains one
of the various icon resources.  (I only know of 6 family members... Maybe Apple's coming out
with 24x24 icons?  icm#'s?) Leave as NIL any members that your family doesn't contain.
Since notification only uses the small icons, only three of the fields are worth filling in.
(Yes, I suppose this might change with a future version of the notification mgr, maybe that
displays a larger icon in the notification dialog, or on systems that have really tall menu
bars).
I don't recall what goes where with the larger icons, but for the ics-'s:
            h[4] = GetResource('ics#', which);
            h[5] = GetResource('ics4', which);
            h[6] = GetResource('ics8', which);
(This is C, with a zero-based array).
Usual disclaimers apply.  Apple probably had some reason for not documenting the icon
family handle to which I am not privy, but this is what works right now.  You probably
shouldn't try this using 6.0.x or in the presence of small children, housepets, or persons
with weak hearts.

We are having problems printing from our Macs to laserprinters over
appletalk. It doesn't matter if the laserprinters are in the same zone
or in a different zone than the Mac. There are several errors that will
be displayed. (randomly?).The most occuring errors are:

"Problems with appletalk"    or
"A printing error occured"   or
The mac just beeps and stops the printing      or
A complete system hang-up.       or

a combination of the above.

Those errors seem to be completely random, sometimes printing goes
without problems for half an hour. than the errors start, giving
the different errors randomly.

The only thing we can do is keep trying to print because 1 in every 10
times it will go through.

Does the mac get influenced by the position of the sun/moon, or the
winddirection or something? It sometimes looks like it.

I am curious. Which version of Apple Share are you using. I know that we had
trouble running Apple share 3.0 and using the *feature* print spooler. We shut
off print spooler in Apple Share  3.0 and remove print monitor from all the
machines in the lab. You might try that. Let me know.

This looks exactly like a situation I had with a network of 25 macs
with several printers. Trouble was finally diagnosed by polling all
nodes on the net from one end of the backbone. The responses to the
poll can be read out on an oscilloscope. What you look for is marginal
signal amplitude coming back. The "normal" vs troublesome signal
strengths will be visually very clear. Find a bad wire or connection
and repair. The trouble is that Appletalk is a very forgiving protocol
and will tolerate lots of noise without any noticable effects. But
printer packets get lost and ...

I also had some success with a 230kHz signal source and a 'scope
to find and fix problems. Usually the net showed about 0.1v drop
from node to node, each node getting "fainter" as the signal source
was moved further from the 'scope. The bad link showed a much higher
drop.

If you are having net problems, this is a pretty good basic check
since it validates the _physical_ network layer (or is that _electrical_,
oh well I'm splitting hairs...). E-mail me if you have questions,
this newsgroup ages off my host pretty quickly and I'm liable to miss
a posted reply. Good Luck!!!!!

Hi once again netters.  While in the process of writting my graphing program, I
was browsing through ResEdit setting up some of my menus.  For my "Styles"
menu, I want to be able to support the standard QD text styles PLUS Double
Underline and Strikethrough!! However, as you may well know, these styles are
not in ResEdit for me to put them in the menu, nor can I find info on how to
implement these styles.  Some Word Processing programs (MS Word, WordPerfect,
etc.) have these in the menu and so do some drawing programs (SuperPaint).
Does anyone know where I can find info on 1) how do display this in my style
menu (do I have to write my own MDEF [man I hope not, could someone supply with
this if that's what is necessary] ) and 2) how to implement these extra styles
in my program.

Subject: Playing non-MIDI frequencies
Date: 4 Mar 92 16:05:59 GMT
Organization: Bell Communications Research, Red Bank, New Jersey

Help, I feel betrayed.  I want to play some pure sine-waves of frequencies
which are not "standard" MIDI frequencies (I'm trying to simulate a telephone
touch-tone keypad) and I'm having some problems.

I figured the way to do this would be to build a pure sine-wave wave table,
and then start playing the appropriate frequencies on mouse-down and stop
them on mouse-up.  Seemed logical at the time.

So, I successfully opened a sound channel to the wave table synth, successfully
loaded in the sine-wave table, and successfully played the notes at the MIDI
frequencies.  But, unfortunately, the touch tone keypad frequencies are not
MIDI notes, so I need a way to specify the frequency without using a MIDI
value.

According to IM V, there is a sound manager command "noteCmd" in which you can
specify *either* a MIDI value *or* an actual frequency as well as the
amplitude.  But, according to IM VI, the value assigned to "noteCmd" is now
used for "freqDurationCmd" and the parameters are now for duration and
MIDI value *only.*  Can this really be?????

This appears to be a completely needless compatibility problem as well as a
step *back* in Sound Manager functionality.  Why would they do this, and is
there *any* way now that I can play sine waves at arbitrary frequencies?

Frustratedly yours,

It's true.  According to a document on AppleLink (which I unfortunately
don't have here right now), the actual frequency is not supported.
Actually, if I remember correctly, it never was.

In any case, your best bet would probably be to create a sampled sine
wave in a 'snd ' resource of the frequency you need.  I believe
HyperCard's old phone dialer stack used such sounds.  If you don't want
to go to the trouble of making up seven sine waves (and playing two at a
time), you can fudge it by changing the sampleRate value before playing
the sound--but you didn't hear that from me.

For example, if your 'snd ' sine wave is sampled at 22 KHz, and is a
1000 Hz tone, the sampleRate field will be 0x56EE8BA3 == 22254 Hz.
Multiply that by 1000/1100 and you get about 0x4F0767A8.  Plug that into
sampleRate and execute a bufferCmd.  The resulting tone should be about
1100 Hz.  If you don't do anything silly like initializing the channel
with initNoInterp or initNoDrop, the Sound Manager will even interpolate
for you and make it sound OK.

But be careful when you write into those structures, don't do it when
sound is playing, I don't know what would happen.  Like I say, you
didn't hear this from me...

Just to nit-pick here. There's no such thing as "MIDI frequencies."
MIDI note commands just indicate which keys to gate on a (virtual)
keyboard. The frequencies emitted by a sound generator might be
totally unrelated to them.

In article <[e-mail]>,
[e-mail] () complains that freqDurationCmd (nee noteCmd)
does not let you specify frequencies other than those corresponding to
integral MIDI note numbers.

It's true, this is a nuisance, but it is possible to get around it,
by using rateCmd instead of freqDurationCmd.

First of all, turn off the sound volume on the channel by doing an ampCmd
with an amplitude of zero. Next, start an infinite-duration sound playing at
some arbitrary pitch with freqCmd. Then, change the note to the right
frequency with rateCmd. Finally, make the sound audible with another ampCmd
with a nonzero amplitude.

This is off the top of my head--the code I wrote that did this is at home.
Then, of course, you need to figure out a way to cut the note after the
right duration. I didn't have this problem, as I was playing a note for
as long as the mouse button was down.

Sound Manager won't do this - you can only play notes or samples at the
MIDI note numbers. For playing sine waves, the thing to do is probably to
build a wave table at your frequency and play it at a standard rate.
Apparently the math for playing arbitrary notes at arbitrary frequencies is
very hairy and would be too taxing to play in real time.

For the telephone touch-pad, you might be better off sampling the pitches
that a real phone creates and playing back the samples.

Well, I don't work for Apple (anymore), so don't take this as gospel,
(but I did design and write the first version of the Sound Manager :-) )...

Yup, you can play ANY frequency you want!  Instead of specifiy the
midi note number in param2 (the long param in a SndCommand) you specify
a fixed point frequency (16.16 bits, i.e.: 442.5 Hz is $016A 8000).

Realize that for touch-tones (DTMFs) you really have to play two tones
at once.  (Sorry if that was obvious...)

With all due respect to Mark, this is definitely incorrect in systems
older than (I'm guessing) 6.0.4. Try passing a value in param 2 and watch
the sound manager code. The bits get stripped off and only the low 7 get
examined. The sound manager then does some odd math (it looks odd because
I'm sure it is optimized to do fixed-point without SANE). It only responds
properly to values 1..128. Values 128..256 map back to lower notes. Larger
values produce strange results.

This is why it would probably be better to sample the tones - it might be
touchy to get the two sine waves synchronized to produce just the right
beat frequencies.

This is a Pascal unit I wrote a LONG time ago to play touch tones out the Mac's

There's an easier method.  Get the 'snd ' resources out of HyperCard 2.0 or
later.  It contains samples of the actual telephone frequencies.  You knew
that HyperCard supported the "DIAL" command didn't you?  Well it does,
and it does it using a simple method.

So, ya wanna do dial tones just like HyperCard? Well, that's not so hard (as
long as you are patient enough to read through all the Sound Manager documents
and beat your head against the wall for half an hour, like I did). The
technique is simple: lift the 'snd ' resources from HyperCard and use them to
generate dial tones! (Yes, that's OK, dtmf tones are generic sounds; just
don't lift any of the other sounds!)

Start by using ResEdit to copy 'snd ' resources #130-145 from the HyperCard
program file (I got them out of 2.0). Next use the Sound Manager to play them
and to use them as an instrument definition for the samplesynth. Since this
can be tricky, and since you may or may not want dive deep into the Sound
Manager, I am including a generic subroutine that I wrote that will "dial" for
you. All I ask is that if you use it "as is" in your application, please
remember me in your prayers.

How to use the dial procedure:

To call the dial procedure simply pass it a string and it will do the rest.
All digits A thru D, # and * play the proper tone for the touch tone key; any
other characters generate a 1/2 second delay. Each tone is sounded for about
1/4 second. The interface to it is simply: Procedure Dial(theNum:Str255).
Please note that in order to keep this short, very little error checking has
been added, please add any/all that you need.

And now for the fabulous source code:

PROCEDURE Dial(theNum: Str255);

VAR
    i                  : Integer;
    theSound           : Handle;
    theResNum          : Integer;
    dummy              : LongInt;
    err                : OSErr;
    chan               : SndChannelPtr;
    cmd                : SndCommand;

BEGIN
    IF Length(theNum) = 0 THEN
        Exit(Dial);

    chan := NIL;        {allocate a channel}
    err := SndNewChannel(chan, sampledSynth, 0, NIL);
    IF err <> noErr
        Exit(Dial);

    FOR i := 1 TO Length(theNum) DO BEGIN

        CASE theNum[i] OF
            '0'..'9': theResNum := ord(theNum[i]) - ord('0') + 130;
            'A'..'D': theResNum := ord(theNum[i]) - ord('A') + 140;
            '*': theResNum := 144;
            '#': theResNum := 145;
            OTHERWISE theResNum := 0;
        END;

        IF theResNum <> 0 THEN BEGIN
            {Load the proper sound resource}
            theSound := GetResource('snd ', theResNum);
            HLock(theSound);

            {See sound manager docs for resource format of}
            {type 2 sounds for more info}
            cmd.cmd := soundCmd;
            cmd.param1 := 0;

            {This next line ASSUMES it was a format 2 'snd ' resource}
            {This will not work for other 'snd ' resources}
            cmd.param2 := ORD4(theSound^) + 14;
            err := SndDoImmediate(chan, cmd);

            {Now send the freqDurationCmd to play a middle C}
            {that's how the instrument was defined in HyperCard}
            cmd.cmd := freqDurationCmd;
            cmd.Param1 := 4000;                 {2 seconds in duration}
            cmd.Param2 := $FF000000 + 60;       {Loud + Middle c}
            err := SndDoImmediate(chan, cmd);

        END ELSE
            Delay(30, dummy);   {all nonDTMF characters produce a delay...}
    END;
    err := SndDisposeChannel(chan, false);
    HUnlock(theSound);
END;
