PPP NULL modem Dial-out

Akshat Bisht

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

    @ Tamir,

    are you using the PPP over NULL-MODEM? Are you dialing out to windows? If so, please help me with a step-by-step guide...

    I'm able to dial-in into the keil board from windows using a "Direct cable connection b/w 2 comps..". But not the other way round.

    Thanks and regards,

    Akshat

    But what about the Windows PPP Dial-up networking? Have you tried it? I have and I had problems until I have connected also the missing RS232 signals.

    OK to clear up some things here is what i did:
    WORKING:
    Under windows:
    1. Installed a NULL MODEM.
    2. Setup a new ppp dial-up connection using that modem.
    3. Dial out using username-"Keil", password-"keil"

    On uVision:
    1. Setup ppp.
    2. init_TcpNet()
    3. init_modem()
    4. modem_listem()
    5. ppp_listen("","Keil","keil")

    NOT WORKING:
    Under Windows:
    1. NULL MODEM installed
    2. setup "incoming connections" on COM1
    3.Add a user to incoming connection - Keil(keil)

    On uVision:
    1. init_TcpNet()
    2. init_modem()
    3. tout=1;
    4. while (1) { timer_poll (); main_TcpNet (); modem_dial(""); if(modem if (tick == __TRUE) { if (ppp_is_up() == __FALSE) { IOSET1 = 0x55<<16; if (--tout == 0) { /* Connect to PPP server. */ ppp_connect ("","Keil","keil"); tout = 50; } } else { IOSET1 =0X20000;//my own }

    tick = __FALSE; } }

    Suggestions? faults?

    Thanks and regards,

    Akshat
