Thanks Mark!

This one works on Windows using COM port. I didn't know that one can use a serial port in Linux more than by 1 application.
So on Windows I just disconnect from the device by setting its CNT asyn record to 0. Then reconnect. Neat!

Is this a local serial port, or on a terminal server?  What operating system?

You should be able to do disconnect from the device in asyn with pasynCommon->disconnect(), and that should free up the serial port for other applications.  You may not even need to do this if the OS lets more than 1 application use the serial port at once.

Hello Mark, gentlemen


I am connecting to a device over RS232 using ASYN.
Can I disconnect from the device without stopping the IOC and connect to the device via Python for example?

I want to save the waveforms from an oscilloscope by other means than EPICS (Python). Then, when I have saved them, I want to use the device again by means of EPICS.
