The following diagrams depict the cabling required for hardware handshaking between your Macintosh and your modem.
Serial port pin connections for Macintosh Plus, SE, II, Quadra, LC, Classic, and PowerBook computers using the mini-8 connector. The Hurdler HQS and QuadraLink NuBus serial expansion cards also use this serial port.
NOTE: The Macintosh SE, II, and Quadra connect pin 7 to General Purpose Input ( GPI).
Serial port pinouts for the Macintosh 128K and 512K computers using the DB-9 connector. This serial port does not support hardware handshaking.
Cable diagram for hardware handshake. This diagram shows the minimum requirements for a hardware handshake cable.
Other variations include:· Connect Macintosh DTR to both Modem RTS, and Modem DTR.
· Connect Macintosh pin 7 ( General Purpose Input) to Modem pin 8 (Carrier Detect). The Macintosh Plus, and some newer Macintosh models ( LC, PowerBook, Classic ) do not support pin 7.
