PPP NULL modem Dial-out

Hello,

I'm trying to setup PPP over NULL modem. Till now i can dial-in to my keil MBD2100 with LPC 2129, over a NULL modem cable in windows and get my http-server to show my index.htm.

When i setup incoming-connection in windows and use the following code, nothing happens:

<snip>
init_TcpNet();

init_modem();

ppp_connect(NULL,user,pass);

while(1)
{ timer_poll(); main_TcpNet();
}

</snip>

Thanks

Akshat
