1. Hello.

   I need help.

   as
   I can connect to gc864 16f8440 Packed connected to USART
   This is my scheme.

   thanks

   1. Take care that C103/TXD is serial data input into module and C104/RXD is serial data output to DTE.

      *NOTE:
      According to V.24, RX/TX signal names are referred to the application side, therefore
      on the GE864 side these signal are on the opposite direction: TXD on the application
      side will be connected to the receive line (here named TXD/ rx_uart ) of the  GE864
      serial port and vice versa for RX.
