Method Detail

connect

public void connect(String host,
                    int port)
             throws TelnetClientException

connect to the telnet daemon.

Parameters:

host - host machine's IP name

port - TCP port number

Throws:

TelnetClientException - if there is an IO error

disconnect

public void disconnect()
                throws TelnetClientException

disconnect from the telnet daemon.

Throws:

TelnetClientException - if there is an IO error

receiveChar

public char receiveChar(int tioTimeout)
                 throws TelnetClientException

receive data from the remote telnet session.

Parameters:

tioTimeout - number of milliseconds to wait for a character to arrive before throwing an exception. 0 means wait indefinitely.

Returns:

a character received from remote telnet session

Throws:

TelnetClientException - if there is an IO error or if a character does not arrive in the allowed time.

sendString

public void sendString(String data)
                throws TelnetClientException

send data to the remote telnet session.

Parameters:

data - the string to send

Throws:

TelnetClientException - if there is an IO error

isSocketInherited

public boolean isSocketInherited()

true if the ConnectClient should inherit the socket used for the telnet connection. This method always returns false if called before connect or after disconnect.

Returns:

true if the ConnectClient should inherit the socket used for the telnet connection

getSocket

public Socket getSocket()

get the socket used by the telnet client. This method returns null if called before connect or after disconnect.

Returns:

get the socket used by the telnet client

getCipher

public com.sas.net.crypto.CipherInterface getCipher()

get the cipher object used by the telnet client. This method returns null if called before connect or after disconnect.

Returns:

get the cipher object used by the telnet client
