Questions tagged [javax.comm]

javax.comm is the Java Communications API. This API allows Java to access serial and parallel ports, and perhipherals attached to serial and parallel ports, including smartcards, modems, and fax machines. This API predates the JCP, so it doesn't have a JSR.

For more information about the Java Communications API, visit Oracle's page.
