TelnetHost (NetPhantom® 8.0 Java API Specification)

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

All Methods Instance Methods Abstract Methods
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.
