Thanks for the great library, I am facing problem in running two instance on a single machine with different com port, application is generating error com.serialpundit.core.SerialComException: C:\Windows\TEMP\sp_tuartx1\spcomwinx64.dll at com.serialpundit.serial.internal.SerialComPortJNIBridge.loadNativeLibrary(SerialComPortJNIBridge.java:393) at com.serialpundit.serial.SerialComManager.(SerialComManager.java:382) at ecibautomatebs.ECIBFetchCNIC.Port(ECIBFetchCNIC.java:31) at ecibautomatebs.ECIBFetchCNIC.FetchCNIC(ECIBFetchCNIC.java:98) at ecibautomatebs.ECIBFetchCNIC.main(ECIBFetchCNIC.java:52) Caused by: com.serialpundit.core.SerialComException: C:\Windows\TEMP\sp_tuartx1\spcomwinx64.dll at com.serialpundit.serial.internal.SerialComPortJNIBridge.loadNativeLibrary(SerialComPortJNIBridge.java:355) ... 4 more Caused by: java.io.FileNotFoundException: C:\Windows\TEMP\sp_tuartx1\spcomwinx64.dll (The process cannot access the file because it is being used by another process) at java.io.FileOutputStream.open0(Native Method) at java.io.FileOutputStream.open(Unknown Source) at java.io.FileOutputStream.(Unknown Source) at java.io.FileOutputStream.(Unknown Source) at com.serialpundit.serial.internal.SerialComPortJNIBridge.loadNativeLibrary(SerialComPortJNIBridge.java:335)

Please suggest how can i get off of this error. My limitation is to use single machine as send and receiver with continuous running service.

Thanks

Please use different names for native libraries when creating SerialComManager instance. Documentation (Javadocs) have all the info.
