Hi,

I followed How to use an ASYN record to communicate with a message-based instrument to build my example. However while running, it reminded that autoConnect could not connect after drvAsynSerialPortConfigure was executed. I did not know how it happened and also how to fix the problem. Could someone please tell me what should I do? Thanks a lot in advance.
