This is mostly similar to WiFi shield library. When sending a multicast packet, replace udp. When listening to multicast packets, replace udp.
The native serial support happens via a piece of hardware built into the chip called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.
The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality hence the name "SoftwareSerial". It is possible to have multiple software serial ports with speeds up to bps.
A parameter enables inverted signaling for devices which require that protocol. The version of SoftwareSerial included in 1. Limitations The library has the following known limitations: If using multiple software serial ports, only one can receive data at a time.
Not all pins on the Mega and Mega support change interrupts, so only the following can be used for RX: Not all pins on the Leonardo and Micro support change interrupts, so only the following can be used for RX: AltSoftSerial overcomes a number of other issues with the core SoftwareSerial, but has it's own limitations.

AT+COPS? – returns currently registered operator details AT+COPS=?
– returns all the operators available. Sending SMS with SoftwareSerial. In below code delay of 1 second is used after each command to give necessary time .
Here in this project we are going to build a Arduino based vehicle accident alert system using GPS, GSM and accelerometer. It can also be used as a Tracking System and much more by just making few changes in hardware and software.

A New Software Serial Library for Arduino. News: NewSoftSerial is in the core!
Starting with Arduino (December, ), NewSoftSerial has replaced the old SoftwareSerial library as the officially supported software serial library.
