 ### Output and Input
 
-* Via `print()` and `println()` you can output text on the telnet server.
+* Via `print()`, `printf()` and `println()` you can output text on the telnet server.
 * To receive and parse input from the telnet client you can add a handler via `onInputReceived()`.
 * By default, the library waits for a newline character from the client, and sends data to the callback handler one line at a time. This behaviour can be deactivated by calling `setlineMode(false)`.
+* A default newline character `'\n'` is used to determine the end of a line. This can be overridden by by calling `setNewlineCharacter('\r')` where `'\r'` can be swapped with any character.
