/**
 * Test the PppSocket implementation.
 * <p>
 * This is a self test, such that it is used to test against A running "server"
 * example.
 * <p>
 * Because the transport layer is essentially devoid of comms protocol, a fixed
 * length string is sent and received, and compared.
 * <p>
 * This expects a dial-up-connection to exist called "junit"
