Waiting for modem to become available
After I go to Print, and then Fax PDF... the fax queue says "Waiting for modem to become available". The Print & Fax preferences show "in use". The fax status in the menu says "idle". It does not dial, it just hangs there.
I've reset the printing system, deleted modem preferences, repaired permissions, tried from a second (blank) user account, rebooted multiple times, and spend an hour on the phone with Apple without managing a single fax.
Unplugging the modem while it's stuck results in the modem pausing. Plugging it back in it stays paused, until I click Resume Fax, where it goes to "Preparing to send the fax document". Clicking Pause Fax after that changes it back to "Waiting for modem to become available", and the menu status changes to "Hanging up..." where it hangs for several minutes, and then changes to "Idle" again.
Any assistance or advice would be greatly appreciated.
Thank you.
