To connect a serial device

The OmniBook 9-pin serial port is a standard serial port, just like those found on
many PCs. 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 port names (COM1, COM2,
COM3, and COM4) assigned to the serial port and infrared port.
