Class TelnetClient

java.lang.Object
com.oroinc.net.SocketClient
com.oroinc.net.telnet.TelnetClient
Direct Known Subclasses:
FTP

public class TelnetClient extends SocketClient
The TelnetClient class implements the simple network virtual terminal (NVT) for the Telnet protocol according to RFC 854. It does not implement any of the extra Telnet options because it is meant to be used within a Java program providing automated access to Telnet accessible resources. A telnet client implementing extra options and meant for use with a terminal emulator can be found in NetComponents Pro TM

The class can be used by first connecting to a server using the SocketClient connect method. Then an InputStream and OutputStream for sending and receiving data over the Telnet connection can be obtained by using the getInputStream() and getOutputStream() methods. When you finish using the streams, you must call disconnect rather than simply closing the streams.
