You can also clear, check, and set the forbidden state of channels using the following commands:

•
channel.getforbidden() (on page 11-62)
•
channel.setforbidden() (on page 11-90)
How do I know if an error has occurred on my instrument?
If you are using TSB Embedded, error messages are displayed in the Instrument Output box when
they occur.
If you are using another remote interface, you might need to use commands to retrieve the error
messages. You can use the commands
errorqueue.count (on page 11-235) and errorqueue.next()
(on page 11-236) to retrieve the number of messages and the text of the messages.
To set the instrument to automatically send generated errors, set localnode.showerrors (on page 11-
291) to 1 (enabled).
To set the instrument to automatically send prompts after each command message, set
localnode.prompts (on page 11-288) to 1 (enabled).
