Package org.apache.commons.net.telnet

Class TelnetOutputStream

java.lang.Object

java.io.OutputStream

org.apache.commons.net.telnet.TelnetOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

final class TelnetOutputStream
extends 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
