I wanted to shut off by command OFF, but it's not possible. Error: Not supported ! Any idea how it works ? Thanks for you help !
Shuting off with OPL
OFF is not supported anymore in ER6. This is documented in the OPL 6 porting quide (section 4.12):
"The Crystal devices do not turn �off� in the same way as previous ER5-based devices. Instead they have a more complex system of phased power-down for items such as the screen. Currently, the OFF keyword does not support these new power-down features and so should not be used in OPL programs. If your code does call OFF then you will receive a Not Supported (KErrNotSupported%) error."
