On a related note, be aware that AppleLink wants to use hardware handshaking.
The typical modem cable is wired for DCD/DTR, so AppleLink will hang while
trying to initialize the modem.

To fix, either
- tell the modem to keep DCD turned on (AT &C0 &W should do it),
- use another cable,
- patch AppleLink.
