You need to configure them to use an unused COM port. Non-PnP internal modems have jumpers on them for setting the resources to use. 7 lists the IRQ and I/O port addresses of the standard COM ports installed. A PnP modem is usually assigned an appropriate COM port and associated resources automatically through the operating system. 7: Standard COM Port IRQ and I/O Addresses COM Port IRQ Address I/O Address COM1 4 3F8–3FF COM2 3 2F8–2FF COM3 4 3E8–3EF COM4 3 2E8–2EF External modems use an existing serial port (legacy serial port or USB), so they don’t have the configuration problem with IRQs and I/O addresses.

23. 24. By external devices, we mean that each has its own power supply. 5 meters) stub cables to run between the devices in a daisy chain (rather than one long cable with several connectors). The effect is the same. The adapter and the last device in the chain (which has only one stub cable attached to it) must be terminated. 25). Most adapters have connectors for both internal and external SCSI devices—if yours doesn’t have both, you’ll need to see if anybody makes one that will work with your devices.

External cabling uses thick, shielded cables that run from adapter to device to device in a fashion known as daisy-chaining. Each device has two ports on it (most of the time). When hooking up external SCSI devices, you run a cable from the adapter to the first device. Then you run a cable from the first device to the second device, from the second to the third, and so on. Because there are two types of cabling devices, you have three ways to connect them. The methods differ by where the devices are located and whether the adapter has the terminator installed.
