TA6530 Emulation

This chapter describes features of the Tandem 6530 terminal emulation.

Session Configuration

WBT Mode

This section describes the basic procedure for creating a session configuration when the terminal is in WBT mode. The options available are described in detail in chapter 2.

1. Click the Configure tab in the Terminal Connection Manager then click the Add button to display the New Connection dialog box.

2. Select Terminal Emulation Client and click OK. The Terminal Emulation Client Connection Wizard - Connection Information dialog box will be displayed.

3. Enter a name which will identify this session configuration for future selection in the Connection Name box.

4. Select the TA6530 terminal emulation in the Emulation list box.

5. Click Next to display the Host Information dialog box.

For a TCP/IP connection, click the TCP/IP button, enter the name or internet address of the host computer in the Host Name box, then click Advanced for additional Telnet options. Refer to the TCP/IP Connection Settings section in chapter 2 for details.

For a serial connection, click the Serial button, specify the communications port in the Connect To box, then click Advanced for additional serial options. Refer to the Serial Connection Settings section in chapter 2 for details.

Make the relevant selections then click OK to return to the Host Information dialog box, then click Next.

6. The following four dialog boxes provide further configuration options which are described in chapter 2. Click Next to advance through the dialog boxes.

7. When you have made your selections, click Finish to return to the Terminal Connection Manager.

8. In the Terminal Connection Manager, display the Connections list, select the session name you specified earlier in step 3, then click the Connect button.

The Tandem 6530 emulation is configured using the TA6530 Settings dialog box which is described in the Setup Menus chapter.

Non-WBT Mode

This section describes the basic procedure for creating a session configuration when the terminal is not in WBT mode. The options available are described in detail in the Setup Menus chapter.

1. Display the Settings menu from the command bar and select Emulation... to display the Emulation Settings dialog box.

2. Select the TA6530 terminal emulation in the Alpha Emulation list box.

3. Display the File menu from the command bar and select New Connection to display the New Connection dialog box.

4. Select the type of host connection required in the Type list box.

For a TCP/IP connection, select TCP/IP, enter the name or internet address of the host computer in the Connect To box, then click Configure for additional Telnet options. Refer to the TCP/IP Connection Settings section in chapter 2 for details.

For a serial connection, select Serial, specify the communications port in the Connect To box, then click Configure for additional serial options. Refer to the Serial Connection Settings section in chapter 2 for details.

5. When you have specified the required settings in the New Connection dialog box, click the Connect button to make the connection.

Note: You can save these settings as a connection template using the Save Session As dialog box. Refer to the Setup Menus chapter for details.

The Tandem 6530 emulation is configured using the TA6530 Settings dialog box which is described in the Setup Menus chapter.

The Status Line

The last (25th) line in the window is used to display messages and status information. You can enable or disable display of a border which separates this line from the rest of the lines above it by setting the Status Border option in the TA6530 Settings dialog box accordingly.

The status line is divided into two fields. The first and leftmost field is used to display messages of up to 64 characters in length. The second field displays the current operating status and will usually display at least one of the following status indicators:

ANSI The emulation is operating in ANSI mode.

BLOCK The emulation is operating in Block mode.

CNTRL Display controls mode activated. In this mode, received control codes will be displayed but not actioned.

CONV The emulation is operating in Conversational mode.

HOLD Hold screen is activated. The emulation stops processing incoming data when the Ctrl + S keys are pressed in ANSI mode. To release the hold state and continue normal processing, press Ctrl + Q.

INS Insert mode is activated. In Block mode, keyboard entered characters are inserted at the cursor position without overwriting already existing characters.

LOCKED The keyboard has been temporarily locked by the application.

NUM Num lock is activated. Num lock is toggled on and off by pressing the keys Alt + Num Lock.

PROT Block Protect mode enabled. Refer to the Block Mode section for details.

When the emulation detects an error, the status line will be temporarily replaced by an error line which will display one of the following messages:

INVALID LANGUAGE SET REQUESTED

You tried to use an invalid national character set.

INVALID DATA

You tried to enter an invalid character in the current field when in Block protect mode.

Operating Modes

The Tandem 6530 emulation operates in one of three main modes, Conversational, Block, or ANSI. Conversational and Block modes are normally used for applications running on a NonStop host system, and ANSI mode for applications running on the LXN host system.

Conversational Mode

In Conversational mode, characters are sent to the host as you type them. This is useful when applications need to interact with you on a character, word or line-by-line basis.

Display memory is treated as one long page consisting of 400 lines, of which 24 lines may be viewed at any one time. Lines above or below those currently displayed may be scrolled into view using cursor or display control keys. Once all the display memory has been used, new data will force all previous lines of data up one line so that the first line is erased, ensuring that the oldest data is erased first.

The status line will display CONV when you are in Conversational mode.

Block Mode

In Block mode, characters are stored in a communications buffer and are not transmitted to the host until the application requests them. The characters are then sent as a block. This enables you to enter a large amount of data and edit it locally before it is transmitted.

Block mode has two sub-modes: Block Nonprotect and Block Protect. In Block Nonprotect mode you can enter any type of character at any position on the screen (except on the 25th line). In Block Protect mode the application divides the screen into protected and nonprotected areas called fields. The cursor cannot be moved into protected fields, which may contain prompts or information or be empty. The cursor can only be moved into unprotected fields, which may also define the type of characters that can be entered.

In Block mode, display memory is divided into pages, the number of pages being determined by the application.

The status line will display BLOCK when you are in Block mode, and PROT when in Block Protect mode.

ANSI Mode

In ANSI mode, characters are sent to the host as you type them, and standard ANSI (American National Standard Institute) functions are executed. Applications that run on the LXN host system generally recognize and use these functions.

The status line will display ANSI when you are in ANSI mode.

Keyboard Mapping

The following illustration shows where TA6530 keyboard functions are mapped to keys on the 101/102 key Enhanced AT keyboard layout. Special key functions that are provided on the TA6530 keyboard can be mapped to any key on your keyboard by using the TA virtual key names listed in the Define Keyboard Macros dialog box.
