COM2 is /dev/ttyS1, and so forth. Other options may also apply depending on your Linux configuration. If you're not sure which port to use, try the /dev/ modem device. Often this device name is a link to the correct port. 2. Choose a connection speed from the Connection Speed drop-down list. The higher the number, the faster your Internet connection will be.
