Hi,

I have already posted this query in many threads but could not get any appropriate solution.

So, I am reposting my query with more details:-

I am using mcf52259 .

I want to connect mcf52259 to modem using serial port .(mcf52259--------------------->Modem)

I took sample code to start ppp in mqx and it works fine when connected to PC.

mcf52259--------serial port--------->PC

Now, i want Mcf52259 to communicate with modem through serial port .

I want to send AT commands from MCF52259 to modem to start ppp & ppp of mqx should syn with modem for further data transfer how to go further with this .

AT command which i am gone send to start PPP in modem is
