I was setting up a friend's new eMac and I noticed a background process in Activity Viewer that I've never seen on any other Mac running Panther. It's called "AppleModemOnHold." It was taking up several megs of RAM, but no CPU cycles at the time?

Does anyone know what the hell this is, what it does, and how to disable it?

If your friend is on a dial-up connection, I believe that process notifies you of an incoming call while online if you have call waiting, and it suspends the internet connection for a few minutes instead of completely disconnecting. When you finish the call, your connection resumes (at least it should) as if you were never off-line. Was the mac online when you noticed that process?

Interesting. I have a Dual 2.0 with a cable modem and I've noticed that process also. I've never even used the built in 56k modem.

The 56k modem wasn't plugged in. They have an ADSL connection.

For the current network configuration, is the internal modem box also checked under the the network port configuration in the network preferences? If not, I can only assume it is related to the DSL modem somehow... but the only thing I can think of that "AppleModem" would apply to is the built in dial-up modem, or possibly bluetooth, if that were available (but that would probably be designated as "Bluetooth"). What is the parent process for AppleModemOnHold in activity monitor?

The parent process is LoginWindow. It's just the process that lets the internal modem put an internet connection on hold to take voice call. I don't know why it's running on my machine even though my internal modem port is disabled, but it is, and I don't care. It takes no CPU time and very little memory.

Since it's a standard part of the OX, my guess is that we all have it. It's nothing to worry about.

I've been curious about this too. If this process is a standard part of the OS, why does it run on my G5 and not on my iBook?
