What exactly is RNif class for? Which connection it monitors? (Actuall GPRS/CSD/RAS connection if any?) Iam connecting via GPRS and I dont use this class, but I am not sure if I handle all cases, so may be I need this class, but I just dont know it. Also I dont understand DisableTimers() method. Which timers are disabled? Also using Start() method which parametrs are used to start a connection?
