Interface TelnetHost

All Known Implementing Classes:

Telnet3270PlayBack, Telnet5250PlayBack, TelnetThread

public interface TelnetHost

The Host Telnet communication. It establishes the connection to the host and initiates the 3270 or 5250 data stream.

Method Summary

Modifier and Type	Method and Description
void	close() Closes the current connection.
void	enableNewEnviron(int codepage, String kbdType) Enables the Telnet NEW-ENVIRON TN5250E negotiation.
String	getDeviceName() Gets the device name of the session.
void	initialize(TelnetInterface i, String terminalList) Initializes the Telnet session after the construction for a 3270/5250 terminal type list.
boolean	isSecured() Checks if the communication is secured with e.g.
void	open(String host, int port) Opens the connection to the host at a specified port number.
boolean	sendSpecialKey(int param) Sends TN3270E special key (param=0 is Attention and param=1 is SysReq).
void	sendSSCPLUData(short[] data, int length) Sends SSCP LU data for a TN3270E session.
void	setAssociatePrinterWithTerminal(String terminalName) Sets associate printer for a printer session.
void	write(short[] buf, int n) Writes an amount of bytes.

Method Detail

enableNewEnviron

void enableNewEnviron(int codepage,
                      String kbdType)

Enables the Telnet NEW-ENVIRON TN5250E negotiation. "kbdType" may be null in order to the the default *SYSVAL keyboard.

initialize

void initialize(TelnetInterface i,
                String terminalList)
         throws IOException

Initializes the Telnet session after the construction for a 3270/5250 terminal type list.

Throws:

IOException - if an I/O error occurs.

open

void open(String host,
          int port)
   throws IOException

Opens the connection to the host at a specified port number.

Throws:

IOException - if an I/O error occurs.

close

void close()

Closes the current connection.

write

void write(short[] buf,
           int n)
    throws IOException

Writes an amount of bytes. The data is appended with and end-of-record (IAC EOR). Each 0xFF character in the buffer is escaped with 0xFF (i.e. IAC IAC).

Throws:

IOException - if an I/O error occurs.

getDeviceName

String getDeviceName()

Gets the device name of the session.

Returns:

null if no device name exists.

setAssociatePrinterWithTerminal

void setAssociatePrinterWithTerminal(String terminalName)

Sets associate printer for a printer session. The printer session will associate to the LU name returned from the TN3270E terminal session.

sendSpecialKey

boolean sendSpecialKey(int param)
                throws IOException

Sends TN3270E special key (param=0 is Attention and param=1 is SysReq).

Returns:

false if this special key is not supported.

Throws:

IOException - if an I/O error occurs.

sendSSCPLUData

void sendSSCPLUData(short[] data,
                    int length)
             throws IOException

Sends SSCP LU data for a TN3270E session.

Throws:

IOException - if an I/O error occurs.

isSecured

boolean isSecured()

Checks if the communication is secured with e.g. SSL.
