get Vcc (milivolts) directly from SIM900 or SIM800L sleep and wake functions for very low power consumption checkPowerUp rewritten to work also with SIM800L or other boards SMS text mode in init function to solve same issues NOTE: I have deleted the hardware serial support as it is only for ATMEGA and only for special pins (special hardware serial port). We need to rewrite to work with other ATMEL IC's and ports.
