NOTE: According to V.24, RX/TX signal names are referred to the application side, therefore on the GE863-PRO3

GSM/GPRS engine side these signal are on the opposite direction: TXD on the ARM application side will be connected to the receive line (here named TXD/ rx_uart ) of the GE863-PRO3 GSM/GPRS engine serial port and viceversa for RX.

TIP: For a minimum implementation, only the TXD and RXD lines can be connected, the other lines can be left open provided a software flow control is implemented.
