Terminal emulation actions
Power Automate provides integration with terminal emulators through the Terminal emulation actions. These actions enable you to handle terminals and mainframes, and perform operations such as moving the cursor, setting and getting text, and sending keys.
Before deploying any terminal actions, use the Open terminal session action to open a new connection with the installed provider.
Important
Before trying to connect to a terminal session, make sure that the actual terminal session is already open on your machine.
If you've installed Micro Focus Reflection on your machine, choose the respective option in the Provider parameter of the action and populate the required configuration.
If you've installed another provider, select HLLAPI that works with most terminal emulation providers.
Depending on the provider you're using, select the appropriate HLLAPI DLL file located in its installation folder. In the following list, you can see the HLLAPI DLL file names of some popular terminal emulation providers:
- RocketSoftware BlueZone: ehlapi64.dll
- IBM Personal Communications: EHLAPI32.dll
- MicroFocus Rumba: System/ehlapi32.Dll
- Cybelesoft zScope: zHllap32.dll
Note
The Windows HLLAPI DLL (WinHLLAPI) is not currently supported.
After opening a terminal session and completing all the wanted operations, terminate the connection using the Close terminal session action. If you don't close the connection, some providers won't let you connect again to the already open session without restarting the software or the connection.

Open a new terminal session.
