My serial ports are blocked

I have a strange problem with the serial ports.
Some weeks ago the RemodeAccess control panel suddenly
refused to open a modem connection, saying that the modem
port was in use by an application. But I couldn't find
the reason. I experimented with differend system configurations
and somehow (I don't know how) I got it to work again. But now I have
the same problem - this time it is the printer port. And now I can't
start any midi software, since the midi interface is connected to
the printer port.
When the computer starts up, just after the desktop is displayed
and before the startup items are executed, the Mac stops for
2-3 seconds and all the lights of the midi interface are flashing.
Probably this is the time when that mysterious application occupies
the port.
It has nothing to do with filesharing, appletalk or a fax software,
since they aren't installed or enabled.

Does anyone know a solution ? I would need a tool that
can display the name of the application that is using a serial port.
Does such a software exisit ? (System Profiler or Tattle Tech don't
have this feature)

Have you turned off AppleTalk? I've had similar problems. I fixed it, but
it's one of those things that I was never quite sure which of the many
things I did caused it to work angain (if any of them).

best,

Did you know you need to turn off Appletalk in the Appletalk control
panel, not just in the chooser? You may have to enable the Appletalk
control panel, restart, then choose remote only in the control panel,
then turn it off and restart again.

Appletalk is disabled.

Yes, it is off. Believe me.
But thanks anyway.

Whatever the program is, it has to be in your system folder to run
during startup. Check the Extension Manager control panel for anything
that you do not recognize and try disabling it. Fax software would act
similar to what you describe. So would AppleTalk. You said that
neither of these are installed (they are automatically installed so I
assume you removed them). If you did removed these from your system,
make sure that no part still remains (even a single extension from
either of these can do it).

Are you using a PowerBook (doubtful since you mention a separate modem
and printer port)? But, if you are, Appletalk must be turned on for
MIDI software to work correctly (I read something about the MIDI stuff
grabbing the only serial port at startup).

What about a recent install. Perhaps the installer placed an
extension in the system folder to automatically connect to the internet
so you can register the new software. Use Find File/Sherlock to hunt
for invisible extensions. Open Find File/Sherlock, select "name"
"doesn't contain" and type "icon." No need to find hundreds of
invisible custom icons. Now select "more choices." Hold down the
Option key, click on the size button, and select "visibility." Start
the search. See if anything looks out of place. If you find something,
use ResEdit to make it visible, drag it to the trash, and restart to see
if your problem goes away.

If none of that helps, you're on your own. I can think of a few other
things, but it would take too long to describe. Good luck.

Peek-a-Boo will at least let you identify the mysterious background process
in question.
