The OmniBook 9-pin serial port is a standard serial port, just like those found on many PCs. You make serial connections to the OmniBook just as you’d make them to a 9-pin PC serial port. The most common types of serial connections involve printers, modems, and other computers. You can make such connections using standard serial cables and adapters available at computer dealers and electronic supply stores. You can use Direct Cable Connection to link two PCs and share files, drives, and printers between them. You can make a serial connection with a serial or null-modem cable (using the COM1 port).
• To start the Direct Cable Connection wizard, click Start, Programs, Accessories, Direct Cable Connection on each computer. One computer must be the "host", and the other computer must be the "guest". To view or change serial port assignments You can see and change the serial communications ports (COM1, COM2, COM3, and COM4) assigned to the external serial connections (serial port, infrared port, and modem cards). 1. In System Properties (click Start, Settings, Control Panel, and then the System icon), select the Device Manager tab. This lists serial (COM) ports. 2. Click Ports. Select the COM port, then click Properties.
(The serial port is typically COM1.) It's best to let Windows 95 automatically resolve serial port conflicts. If it cannot , then you can reassign the serial port resources manually. To do so, open the System Properties for a COM port as above. Display the Resources tab, cancel the automatic setting and select a different configuration number. Click OK and note the new name (such as COM2) assigned to this port. • You can also view all port information in HP User Tools, Information, Resource Allocation. The changes you make to the advanced settings for a serial port should match your hardware settings.
The built-in advanced settings are listed below—you shouldn't use different settings in any applications.
