In the Category list, select Programmer. 3. To allow background programming in devices that support real-time ISP, check the Enable real-time ISP to allow background programming Option. 4. Click OK. For Jam or JBC you must use a -d option in the command line to enable real-time ISP for the actions issued in that same command line. There is a -d option called DO_REAL_TIME_ISP.
