The PPPClient_Init structure is used to open a PPP client session.
The flow control mode XON/XOFF applied to PPP has not been tested. It is not advisable to use it. Since @CHIP-RTOS
1.02B XON/XOFF mode is also available if the DMA receive mode for the selected serial port is enabled, but due to the
internal functionality of DMA it is not possible to immediately detect an XON or XOFF from the peer. Therefore it is possible
that an overrun situation can occur at the connected peer (e.g. GSM modem). We now offer this mode because GSM
modems (any??) support only XON/XOFF flow control.
The PPPClient_Init structure contains an array of the PPPdial structures used for initializing and dialing a modem.
These modem commands will be executed at the start of establishing a connection to a PPP server.
The PPPClient_Init structure also contains a PPP_ModemHangup structures for closing the modem connection.
For how to initialize and use these structures see the PPPCLIE.C example.
