DeleteSMS (FB)

FUNCTION_BLOCK DeleteSMS EXTENDS CBM.ETrigTo

By use of this function block, the committed short message as received with the last mentioned function is deleted.
After starting this function block, it will try to allocate the modem.
When it is free a lock is set and therefore reserved for the currently function block.
After a reset (falling edge on “xExecute”) the lock is released.
