Terminal - Send text |
Declaration
<AMSENDTERMTEXT SESSION="texts" WAITFORDEFAULTPROMPT="Text (options)">"Text"</AMSENDTERMTEXT> |
Description
Sends text to the terminal starting at the current cursor position during an established Terminal session. This action can be set to wait until the terminal is ready to receive the next command before sending text.
Practical Usage
Used to send text into an existing terminal session that was previously created by Connect Terminal action. The terminal actions are used in leu of terminal emulation software. Using the terminal actions, legacy systems can be automated in the background without the use of 3rd party software.

Additional Notes
Terminal Function Keys
Function keys on a terminal may either generate short fixed sequences of characters or the characters they generate may be configured by sending special character sequences to the terminal. On a standard computer keyboard, the function keys may generate a fixed, single byte code, outside the normal ASCII range, which is translated into some other configurable sequence by the keyboard device driver or interpreted directly by the application. The following list contains function keys that this activity can use to send to the terminal by simply enclosing them with with {} (i.e. {ENTER})

Examples
- The sample AML code below can be copied and pasted directly into the Steps Panel of the Task Builder.
- Parameters containing user credentials, files, file paths, and/or other information specific to the task must be customized before the sample code can run successfully.
Example 1
This sample step sends the following text "This is the text to send" to terminal session "MyTermSess." It is set to wait before and after the default prompt appears.
<AMTERMINAL ACTIVITY="sendtext" SESSION="MyTermSess" WAITFORDEFAULTPROMPT="both" TEXT="This is the text to send" />
Example 2
This sample task uses an assortment of terminal activities to automate a terminal logon process. Examining the step parameters and properties of this task may assist you in creating your own terminal emulation task.
