Interactive Command line?

[fumbler]

I'm new so this may be my ignorance showing. How can I call an external program ( a PuTTY SSH session) and see and process the replies?

I have tried System Exec.vi but it only allows me to set the input lines beforehand and then throws them all at the program. After the session exits I can see the whole result. This is not so useful. I need to wait/parse the remote prompt before issuing the next line of input.

Thanks in advance. Pete

If you are on linux, you can use a pipe to communicate with plink (PuTTY Link - a derivative of putty). On windows, some folks are working on supporting pipes from LabVIEW. Nothing working, of production quality, yet.

There's a windows version of expect from ActiveState. I don't know what it costs.

Oh, from the buy page:

Thanks guys. Yes, if I was not restricted to Windows it would not be a big problem. Pete
