The GSM module have two UART channels. One for the
commands, one for debugging. With this jumper you control
which channel goes to PIC18F97J60 or FT232RL.

communication port of the FT232RL chip to the MTX/DTX
controller or to the SIM300D module. Default configuration is
SIM300D module to communicates with FT232RL chip, but if
you wish to use USART communication option of Microchip
TCP/IP stack, you can switch J1 and J2 jumpers. When J1
and J2 jumpers are to 1-2 state - serial communication from
FT232RL chip is connected to the GSM module. You can use
virtual com port for communication with GSM module. The
PIC18F97J60 microcontroller however must release RXD and
TXD pins. When J1 and J2 jumpers are to 2-3 state - serial
communication from FT232RL chip is connected to the
PIC18F97J60 microcontroller. You can use virtual com port for
communication with PIC18F97J60. MTX/DTX and MRX/DRX
jumpers however must be open and you can not communicate
with GSM module.
