Teraterm has a macro application that you can call through System Exec.Basically it is a sort command line version of Teraterm that you can call with command line parameters to execute. Works fine for simple tasks like connecting to a target and executing a few commands, but not for a lengthy data exchange with the device that requires to go back and forth between LabVIEW (or any other application) and the Teraterm Macro executable. Putty is another possibility with similar limitations. Press the UP arrow key to view the command that was entered most recently in the session. Putty can be integrated with LabVIEW through use of standard IO redirection to Pipes, and I have developed an OpenG library to do this redirection but it never quite got fully tested and released. Use the UP and DOWN arrow keys to scroll through a list of up to ten previous commands. Type at least one letter of a command and press the TAB key to scroll through a list of valid commands that match the text you typed in the command line. In the meantime some other people have developed. Net based pipe redirection interfaces which might be able to do that.
