Default values are written in - * italics and other possible values are bold. - *
- *
<PARAM NAME="Fx" VALUE="functionkeytext"> - *
Sets the string sent when the function key Fx (x between 1 und 20) - * is pressed. - *
<PARAM NAME="VTcolumns" VALUE="80"> - *
Sets the columns of the terminal initially. If the parameter - * VTresize is set to screen this may change, else it is fixed. - *
<PARAM NAME="VTrows" VALUE="24"> - *
Sets the rows of the terminal initially. If the parameter - * value of VTresize screen this may change! - *
<PARAM NAME="VTfont" VALUE="Courier"> - *
Sets the font to be used for the terminal. It is recommended to - * use Courier or at least a fixed width font. - *
<PARAM NAME="VTfontsize" VALUE="14"> - *
Sets the font size for the terminal. If the parameter - * value of VTresize is set to font this may change! - *
<PARAM NAME="VTresize" VALUE="font"> - *
This parameter determines what the terminal should do if the window - * is resized. The default setting font will result in - * resizing the font until is matches the window best. Other possible - * values are none or screen. none will let nothing - * happen and screen will let the display try to change the - * amount of rows and columns to match the window best. - *
<PARAM NAME="VTscrollbar" VALUE="false"> - *
Setting this parameter to true will add a scrollbar west to - * the terminal. Other possible values include left to put the - * scrollbar on the left side of the terminal and right to put it - * explicitely to the right side. - *
<PARAM NAME="VTid" VALUE="vt320"> - *
This parameter will override the terminal id vt320. It may - * be used to determine special terminal abilities of VT Terminals. - *
<PARAM NAME="VTbuffer" VALUE="xx"> - *
Initially this parameter is the same as the VTrows parameter. It - * cannot be less than the amount of rows on the display. It determines - * the available scrollback buffer. - *
<PARAM NAME="VTcharset" VALUE="none"> - *
Setting this parameter to ibm will enable mapping of ibm - * characters (as used in PC BBS systems) to UNICODE characters. Note - * that those special characters probably won't show on UNIX systems - * due to lack in X11 UNICODE support. - *
<PARAM NAME="VTvms" VALUE="false"> - *
Setting this parameter to true will change the Backspace key - * into a delete key, cause the numeric keypad keys to emit VT100 - * codes when Ctrl is pressed, and make other VMS-important keyboard - * definitions. - *
<PARAM NAME="Fnr" VALUE="string"> - *
Function keys from F1 to F20 are programmable. You can - * install any possible string including special characters, such as - * - * - * - * - * - *
\eEscape
\bBackspace
\nNewline
\rReturn
- *
<PARAM NAME="CFnr" VALUE="string"> - *
Function keys (with the Control-key pressed) from CF1 to CF20 are programmable too. - *
<PARAM NAME="SFnr" VALUE="string"> - *
Function keys (with the Shift-key pressed) from SF1 to SF20 are programmable too. - *
<PARAM NAME="AFnr" VALUE="string"> - *
Function keys (with the Alt-key pressed) from AF1 to AF20 are programmable too. - *

On how to load a module, please refer to the - * telnet documentation. - * - *
- * - *
Buttons: - *
<PARAM NAME=number#Button VALUE="buttontext|buttonaction"> - *
number is the sequence number and determines the place - * of the button on the row. - *

- *

buttontext is a string displayed on the button. - *

- *

buttonaction may be one - * of the following functions or strings
- * (Note: the backslash character - * in front of the dollar sign is mandatory!) - *
    - *
  • simple text - * to be sent to the remote host. Newline and/or carriage return - * characters may be added in C syntax \n and \r. - * To support unimplemented function keys the \e escape - * character may be useful. The \b backspace character is - * also supported. - * The text may contain field - * reference(s). - *

    - *

  • \$connect(host[,port]) - * tries to initiate a connection to the host - * at the port, if given. The standard port is - * 23. host and port may be hostname - * and number or field - * reference(s). If a connection already exists - * nothing will happen.
    - * (Note: It is not allowed to have - * spaces anywhere inside the parenthesis!) - *

    - *

  • \$disconnect() - * terminates the current connection, but if there was no - * connection nothing will happen. - *

    - *

  • \$detach() - * detaches the applet from the web browser window and - * creates a new frame externally. This may be used to allow - * users to use the applet while browsing the web with the - * same browser window.
    - * (Note: You need to load the applet via the - * appWrapper class or - * it will not work properly!) - *
- *
Examples:
- * (Note: It makes sense if you look at the - * examples for input fields below.) - * 
- *        <PARAM NAME=1#Button VALUE="HELP!|help\r\n">
- *        <PARAM NAME=2#Button VALUE="HELP:|help \@help@\r\n">
- *        <PARAM NAME=4#Button VALUE="simple|\$connect(localhost)">
- *        <PARAM NAME=5#Button VALUE="complete|\$connect(www,4711)">
- *        <PARAM NAME=6#Button VALUE="connect|\$connect(\@address@)">
- *        <PARAM NAME=8#Button VALUE="connect to port|\$connect(\@address@,\@port@)">
- *        <PARAM NAME=10#Button VALUE="window|\$detach()">
- *
- *

- * - *

Input fields - *
<PARAM NAME=number#Input VALUE="fieldname[#length]|initial text[|action]"> - *
number is the sequence number and determines the place - * of the field on the row. - *

- *

fieldname is a - * symbolic name to reference the input field. A reference may be used in - * button actions and - * is constructed as follows: - * \@fieldname@ - * The \@fieldname@ macro will be replaced by the string entered in - * the text field. - *

- *

length is the length of the input field in numbers of - * characters. - *

- *

initial text is the text to be placed into the input - * field on startup - *
action may be used similar to a - * button action. This action - * will be used if the users presses Return in the inputfield. Leave - * empty if you only want to use a button to send the text! - *
Examples:
- * (Note: It makes sense if you look at the - * examples for buttons before.) - * 
- *        <PARAM NAME=3#Input VALUE="help#10|">
- *        <PARAM NAME=7#Input VALUE="address|www.first.gmd.de">
- *        <PARAM NAME=8#Input VALUE="send#5|who|\@send@\r\n">
- *        <PARAM NAME=9#Input VALUE="port#5|4711">

Scripts: - * 
<PARAM NAME=script VALUE="pattern|text|...">
- *
A script contains of pairs of pattern and text strings. - * If the pattern is matched against the output from the remote host, - * the corresponding text will be sent. Each pattern will match only - * once per session. A session is defined by connect and - * disconnect.

- * Thus it is possible to program an autologin as follows:
- * 

"login:|leo|Password:|mypassword|leo@www|ls"
- * Newlines will be added automatically to the string sent! At the - * moment the order of the pattern and text pairs is not relevant. - *

- * It is possible to prompt the user for input if a match occurs. If the - * corresponding text is a string enclosed in braces ([] or {}) a - * dialog window is opened with text as prompt. A special case - * is an empty prompt in which case the pattern will be shown as - * prompt. "[Your name:]" would open a dialog window with the - * text "Your name" as prompt. Curly braces have a special - * meaning; any user input will be shown as "*" which makes - * it possible to program password prompts. Example: - * "{Your password:}".

- * A special match like: "login:|[]" can be used to open a - * dialog and display "login:" as prompt. This works for - * "{}" as well. - * - *

- * If you don't know the prompt ahead of time, you have to do a sequence of - * send() and wait() or receiveUntil() calls. send() sends a string across - * the telnet connection. Add a '\r' to the end if you want to - * complete a command. wait() waits for an exact string from the other side - * of the telnet connection, and returns nothing, - * receiveUntil() also waits for a string, but returns all the data - * that it received while waiting, including the string itself. - * Use this if you want the output from a command. Please note that - * the telnet connection will usually echo the sent command. - *

- * sendLine() is generally better, since it adds the '\r' - * automatically, waits for the prompt before returning, and returns all - * data received before the prompt, with the prompt itself cut off the - * end, and the sent command cut off the beginning. login() and - * sendLine() are implemented using send(), wait() and receiveUntil(). - * They can be freely mixed and matched. - *

- * Here is a simple example of the use of TelnetWrapper: - * 

- * // creates a new file in /tmp, lists the directory to prove it done
- * {
- *   TelnetWrapper telnet = new TelnetWrapper("123.45.78.90");
- *
- *   // setting the correct prompt ahead of time is very important 
- *   // if you want to use login and sendLine
- *   telnet.setPrompt("$ ");
- *   telnet.login("loginname", "password");
- *
- *   // this is how you have to do it otherwise
- *   telnet.send("touch /tmp/TELNET_WRAPPER" + "\r");
- *   telnet.wait("$ ");
- *
- *   // sendLine 1: adds the \r automatically, 2: waits for the prompt
- *   // before returning 3: returns what was printed from the command
- *   String ls = telnet.sendLine("ls /tmp");
- *   System.out.println(ls);
