I have a macintosh that claims that its modem port is in use 'by
another application' whenever I try to access the port, via a terminal
emulator. I have tried rebooting the mac, turning off appleshare and
zapping the pram, all to no avail.
I recall that about 2 years ago, some people had similar problems
after running MIDI software, and that a utility is available to fix
just this problem. I have looked around sumex, the BMUG CD, and the
NYMUG CD, all to no avail.
I would appreciate any pointers to this utility, or any other way to
solve the problem. I would rather not replace a motherboard, which is
the dealer's suggestion.
The mac SE is running system 6.0.5 (or was it 6.0.7), MacTerminal
2.3.1, and is directly connected to our vax via a 9600 baud serial
line.

Are you connected using appletalk? If not check in the chooser to m ake sure appletalk to turned off. Also check to make sure that the imagewriter driver in the chooser is not set up to the modem port. If the imagewriter is se lected as the modem port, the mac may mistakenly think that port is in use when you really try to use a modem. Play around with this. I'm sure your problem lies therein. Good luck, Jason Garms tgoose@eng.umd.edu

Re: Busy Serial Port I seem to remember some discussion awhile back related to MIDI applications locking up the serial port, particularly if exited uncleanly. I don't remember if the problem stayed around from boot to boot. I thought there was a DA or other application that was mentioned that one could run to clear the condition.

Sorry, I tried to e-mail to "denbeste@bgsuvax.UUCP (William C. DenBesten)
but it bounced. I was going to suggest that he and others with a similar
problem (as stat{d in his recent message to the net):

might want to look for a small utility titled "SPConfig" which resets the
serial ports to "normal?" I found it on our local BBS, and think it may well
be available quite broadly. It is very small, about 1.2Kb. and does the job
quite well on MacPlus, SE, SE30, IIci, and IIfx.
Luck

Yup, that's happened to me. Even, sometimes, when exiting cleanly. > I don't remember > if the problem stayed around from boot to boot. Yup. Or the problem can just appear. > I thought there was a DA or > other application that was mentioned that one could run to clear the condition. spconfig_reset will often clear it. Or, running a non MIDI-manager application for a second or two. -- Nick Rothwell, Laboratory for Foundations of Computer Science, Edinburgh. nick@lfcs.ed.ac.uk <Atlantic Ocean>!mcsun!ukc!lfcs!nick ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ ~~ "I see what you see: Nurse Bibs on a rubber horse."

I finally found that it was caused by a noisey power supply. -- = John DeRosa, Motorola, Inc, Cellular Infrastructure Group = = e-mail: ...uunet!motcid!derosaj, motcid!derosaj@uunet.uu.net = = Applelink: N1111 = =I do not hold by employer responsible for any information in this message =
