Method Detail

onCommOpen

void onCommOpen(TelnetComm comm)

Called when the communication link is opened.

Parameters:

comm - The telnet communication instance.

onCommState

void onCommState(SocketCommNIO comm)

Called when the state changes.

Parameters:

comm - Socket communication instance.

onCommConnected

void onCommConnected(TelnetComm comm)

Called when the communication link is connected.

Parameters:

comm - The telnet communication instance.

hostAcceptedDataStream

void hostAcceptedDataStream(TelnetComm comm,
                            String terminalType)
                     throws IOException

The host accepted the options for the terminal type and went into BINARY mode. This means that 3270/5250 data stream will follow. Inform the host session listener of a connect change.

Parameters:

comm - The telnet communication instance.

terminalType - The terminal type accepted by the host at Telnet terminal negotiation.

Throws:

IOException - If an I/O error occurs.

processInboundDataStream

void processInboundDataStream(TelnetComm comm,
                              byte[] inputBuf,
                              int pos,
                              int inputBufLen)
                       throws IOException

Processes the inbound 3270 or 5250 data stream.

Parameters:

comm - The telnet communication instance.

inputBuf - The input buffer.

pos - Start position in buffer.

inputBufLen - Length of input buffer.

Throws:

IOException - If an I/O error occurs.

processInboundSCSDataStream

void processInboundSCSDataStream(TelnetComm comm,
                                 byte[] inputBuf,
                                 int inputBufLen)
                          throws IOException

Processes the inbound 3270 printer data stream. Processing of the buffer always starts at position 0.

Parameters:

comm - The telnet communication instance.

inputBuf - The input buffer.

inputBufLen - Length of input buffer.

Throws:

IOException - If an I/O error occurs.

processInboundSSCPLUDataStream

void processInboundSSCPLUDataStream(TelnetComm comm,
                                    byte[] inputBuf,
                                    int pos,
                                    int inputBufLen)
                             throws IOException

Processes the inbound 3270 SSCP-LU data stream.

Parameters:

comm - The telnet communication instance.

inputBuf - The input buffer.

pos - Start position in buffer.

inputBufLen - Length of input buffer.

Throws:

IOException - If an I/O error occurs.

processPrintEOJ

void processPrintEOJ(TelnetComm comm)
              throws IOException

Processes a Print End-of-Job for 3270 printers.

Parameters:

comm - The telnet communication instance.

Throws:

IOException - If an I/O error occurs.

onCommError

void onCommError(TelnetComm comm,
                 IOException e)

Called when the communication link is closed.

Parameters:

comm - The telnet communication instance.

e - The exception.

onCommClosed

void onCommClosed(TelnetComm comm)

Called when the communication link is closed.

Parameters:

comm - The telnet communication instance.
