Package org.apache.commons.net.telnet

Class TelnetOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    final class TelnetOutputStream
extends java.io.OutputStream
    Wraps an output stream.

    In binary mode, the only conversion is to double IAC.

    In ASCII mode, if convertCRtoCRLF is true (currently always true), any CR is converted to CRLF. IACs are doubled. Also a bare LF is converted to CRLF and a bare CR is converted to CR\0
