I am working on a project which requires communication between client
and server,
I can use two methods ftp client or ppp over serial
communication;
My question is when i have to send and recieve data via modem, what should
be required to do, whther i transfer serial data by modem using PPP or by
sockets. remebere i am using RCM3100 core.
I want to understand basic difference between twos.
Thanks

You're mixing apples and oranges...
Sockets is the programming interface to TCP/IP communication, while PPP
is (one) way to establish a TCP/IP connection between two hosts. This is rather
too simplified, but could help you to understand the
problem.
So. you would use sockets in your program to initiate FTP client
connection to or from your application. This connection could be initiated over
ethernet, or over PPP connection. If you have both of them established, TCP/IP
stack will determine (based on additional information like routing tables etfc)
which way to route packets.
If the only application you're looking at is modem, and if you can
control both sides of connection, I would recommend you not to deal with TCP/IP
stuff - this means bringing in PPP as well, with a whole new array of
problems... Whenewer possible, keep the things simple.

George

Thanks Georges
Yes, There was some confusion.
I am not using TCP/IP. I have used Sockets to
initiate FTP client connection by initiating serial over PPP connection.
I am new in this field so i have some
ambiguities. one of them is:
In the embedded card i have CTS/RTS flow control with
modem, While establishing PPP connection i have mentioned about CTS RTS pins in
ifconfig(....) function. whether i have to use commands like serBflowcontrolOn() or just i can skip it as i am
using ftp client download and upload procedure.
