- The cable in the FAQ is for Dialup Security... that it, it monitors
- CD (DCD) and when dropped, hangs up the line.

- If you want Dialup Security, then you will need to make your own. The reason
- why is because all other cables are created with the MacOS in mind, and the
- MacOS "knows" about all the pins on the modem port.
-
- If you need hardware handshake, then follow the directions of your
- manufacturer. You may also need to setup DTR flow control, depending
- on the handshaking implementation...
