Connecting to other computers and networks is one of the most powerful aspects of computing. Without external access, basic functions such as email and file sharing cannot be performed. To enable users to access information available outside their local machines, Linux supports communication with other computers over telephone lines and networks.
In this module, you will learn how to enable and update serial and non-serial devices using Linux commands and utilities, including the setserial command, the getty program and its variants, and the Network Configurator. You will also investigate differences between serial and non-serial devices in support, configuration, and use.
