Reset the RS-232-C connection

Question

I control the analyzer via RS-232-C.

I perform a single sweep which is triggered by an external trigger. I synchronize to end of sweep with "*OPC?".

Sometimes the external trigger does not come and the "*OPC?" command ends in a time-out.

After this time-out the RS-232-C connection jams.

How can I open the connection again without restarting the analyzer?

Answer

Please send the command "@DCL" after the time-out. This will reopen the RS-232-C connection.
