Initialization of TELIT GM862 module realized with MPLAB MPASM Microchip therefore ASSEMBLER

The PIC is connected to the GM862 through the UART It transmits with the TransWt routine and it receives under Interrupt (ISR) introducing the data in the RAM therefore the pointer will be reseted FSR=0xA0 (in the example comes clear the ram) To notice that in the list there are some verifications of OK answer (check_ok)
