In English

Hi, I m using modbus RTU to get data from DGH6200 module (http://www.dghcorp.com/). I has no problem with com port (COM4) when i m using DGH utility software. I restart my PC then I try on ScadaBR, it show an error {com.serotonin.modbus4j.exception.ModbusInitException: com.serotonin.io.serial.SerialPortException: gnu.io.PortInUseException: Unknown Application}  . Actually last few months i m testing on ScadaBR also, it is pretty good and no problem. But I dunno why now this problem come recently. Any help would be most appreciated.

Error shows a SW is using the IO port - suggestions: hunt it down and kill it before running ScadaBR.

Also, info as Java version, OS and java vendor should help point out any IO problems.

Hi all, 

I solve the problem recently. I change the Java JRE 6 to older version, jre-6u43. The latest jre-6u45 not work.
