Hide comm output from user?

[Merum]

Hi and thanks in advance for your help.

I have a script that writes some parameters into a device, and receives responses from the device. I'd like to be able to hide all of these from the user via the script, so that they cannot reveal them by turning local echo on. Any ideas you can suggest?

If you use the rget command to read data from the port, none of the received information will appear on screen.

Thanks for your response! I'm actully more interested in hiding the "send" side of the communications from the user. Is there an equivalent method for masking what gets sent from the script to the remote device other than having local echo off in the program settings?

About the only thing I can think of is setting the foreground color the same as the background color. You would have to create a profile to do this manually (see the Options | Data Options | Terminal Colors pane in the Setup dialog), then switch back and forth between the "normal" profile and the one with the foreground and background colors identical using the set terminal colors command.
