UI Automation Activities

Last updated Aug 13, 2024

Terminal Session

UiPath.Terminal.Activities.TerminalSession

Description

A container that connects to a terminal and enables you to perform multiple actions within it.

Project compatibility

Windows - Legacy | Windows

Configuration

Designer panel

Configure Connection... - Enables you to set up a connection. Once the activity is dragged into the workflow designer, the Configure Connection window is opened. If closed, it can be reopened by using this option.
Start Recorder - Once a connection is set up, the Start Recorder button can be used to connect to the terminal and record the necessary actions.

Properties panel

Common

Continue on error - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.

Note: If this activity is included in Try Catch and the value of the Continue on error property is True, no error is caught when the project is executed.
DisplayName - The display name of the activity.

Misc

Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

New Session

Connection String - The string that contains the connection details. This field supports only strings and String variables.
Output Connection - The established connection, stored in a TerminalSession variable. This variable can be passed on to other Terminal Session activities in the Existing Connection property field if you want to reuse the connection that is already established. This field supports only TerminalSession variables.

Options

DelayMS - Delay time (in milliseconds) before the activity begins performing any operations. The default value is 1000 milliseconds (1 second).
TimeoutMS - Specifies the amount of time (in milliseconds) to wait for the activity to run before an error is thrown. The default value is 50000 milliseconds (50 seconds).

SSH Connection Properties

SSH Password - The SecureShell password used to connect to the specified terminal, stored in a SecureString variable. This field supports only SecureString variables.
SSH Username - The SecureShell username used to connect to the specified terminal, stored in a String variable. This field supports only strings and String variables.

Use Existing Connection

Close Connection - If this check box is selected, the existing connection is closed after the activity stops execution. By default, this check box is selected. Please note that this property is ignored if the Output Connectionproperty is set.
Existing Connection - Supplying a TerminalSession variable in this property field uses the connection stored in the variable to connect to a terminal. This field supports only TerminalSession variables.

The Configure Connection window

The Configure Connection window contains various configuration options that vary depending on the type of provider chosen for making the connection to the terminal environment.

Properties independent of the chosen provider:

Show client application - If checked, displays a view of the terminal screen at runtime.

The Direct Connection provider

The Direct Connection provider is a UiPath internal provider that does not need any 3rd party terminal emulation software on the robot machine. The emulation is done by the robot, at runtime.

Connection settings

Address - IP address or host name of the terminal environment system.
Port - A port number where the terminal environment system accepts connections.
Type - The type of terminal emulation needed:
- TN3270 - Commonly used by IBM Z-series systems.
- TN5250 - Commonly used by IBM I-series systems (AS-400).
- VT - DEC VT compatible terminals.
- HP Series - HP specific terminal emulation.
- Tandem - Tandem Systems terminal emulation.
- Wyse - Wyse series terminal emulation.
- ANSI - Terminal emulation based on the ANSI specification.
- Sco ANSI - Extension of the ANSI specification used by SCO Unix systems.
Protocol - The communication protocol to be used for the connection:
- Telnet - The Telnet protocol.
- SSH - The SSH protocol used by most Unix/Linux systems.
- HPVT - HP specific protocol used in conjunction with the HP Series terminal emulation.
Terminal Mode - The specific flavor of terminal emulation. The value available here is dependent on the value chosen in the Type field.
Encoding - The code page used by the terminal environment system. The default is IBM037 for the IBM family terminals and ASCII for other types of terminals.
Enable SSL/TLS - Used in conjunction with the Telnet protocol, to specify that the terminal environment system uses an SSL or TLS encrypted connection.
LU Name - The logical unit name, used with the IBM family terminal types.
Answerback - A text message to be sent to the host system when the terminal receives the ENQ control character. The message can contain the Enter control key, encoded in the string value as ^M. This configuration option is available only when the selected terminal type is VT.
Proxy type - The type of protocol used by the proxy server:
- None (default) - No proxy
- Tunnel - HTTPS proxy.
- SOCKS4
- SOCKS5
- SOCKS4A
Proxy Host - IP address or host name of the proxy server.
Proxy Port - The port number used by the proxy server.
Proxy User - The username to be used for authentication on the proxy server.
Proxy Password - The password to be used for authentication on the proxy server.

Note: The Direct connection provider uses a native DLL library that is not signed by UiPath. The library is named ttermdotnet.dll. If you use this provider, you need to allow the loading and execution of this library.

The IBM EHLLAPI provider

The IBM EHLLAPI provider works with any 3rd party terminal emulation software that implements the EHLL API. The details for the implementation of the EHLL API should be found in the 3rd party terminal emulator software documentation.

Note: The terminal emulation software needs to be started and connected before attempting to connect to it via EHLLAPI.

Connection settings

EHLL dll - The path to the dll used for implementing the EHLLAPI in the 3rd party terminal emulator software.
EHLL function - The name of the entry point function in the EHLL dll. Usually, “hllapi”.
EHLL session - The name of the session as it appears in the terminal emulation software. Usually “A”, but when using multiple simultaneous sessions, the value may vary.
EHLL encoding - The encoding used by the terminal emulation software for the given connection.
EHLL enhanced - Used to specify if the 3rd party terminal emulator implements the standard or enhanced version of the EHLL API.
Encoding - The code page used by the terminal environment system. The default is IBM037 for the IBM family terminals and ASCII for other types of terminals.
Basic mode - A mode that disables field level processing for better performance. Field level activities (Get Field, Set Field, etc) are working in this mode.
Run in process - Controls the way the communication with the 3rd party terminal emulation is made via EHLL API. By default, this is disabled and in this case the communication is done via a proxy process, a different executable that is part of the terminal activities package. At runtime, the proxy process communicates with the UiPath Executor process via IPC (inter-process communication). When enabled, communication with the 3rd party terminal emulation software is made inside the UiPath Executor process. This option should be enabled only if the proper functioning of the proxy process is prevented by anti-virus software or by software security policies.
Note: Changing the Run in process parameter to True may result in the terminal session not working properly due to difference in architecture (32-bit vs 64-bit) between the 3rd party emulator and the UiPath Studio/Executor process. 32-bit EHLL libraries only work properly in Windows - Legacy projects, while 64-bit EHLL libraries only work properly in Windows projects.

Note: Due to a limitation in the specification of the EHLLAPI, the enhanced version of EHLLAPI does not support working with multiple EHLLAPI sessions when the Run in process option is checked. Only the standard implementation of EHLLAPI supports such a scenario. This means that the EHLL enhanced option is unchecked and the DLL file listed in the EHLL dll field is a version that implements the standard EHLLAPI specification.
