[RE:] Re: [lwip-users] How to test IP over PPP ?

[Kishore]

Hi all,
It seems, i  made some progress!
Im using ARM7TDMI, in little endian mode.No idea how it would work for big 
endian.

I just changed sio_read in sio.c

u32_t sio_read(void * dev, u8_t * buf, u32_t size)
{
        char str1[]="CLIENT";
        char str2[] = "CLIENTSERVER";
        LWIP_DEBUGF( 1,("sio_read:  Read\n") );
        int vLen = gpUart0->read((char *)&buf[0],size);
        if(vLen > 0)
                if (strcmp((char *)buf,(char *)&str1))
                 sio_write(dev,(u8_t *)&str2,12);
   return vLen;
        
}

and now win2k  ppp direct connection could establish a connection,but anyway 
fails while registering the new remote computer (my embedded system) with error 
code 732.

Error 732: The PPP negotiation is not converging.
The negotiation of PPP parameters did not succeed because the local and remote 
computers could not agree on a common set of parameters.

My Opt.h define
/* ---------- PPP options ---------- */

#ifndef PPP_SUPPORT
#define PPP_SUPPORT                     1      /* Set for PPP */
#endif

#if PPP_SUPPORT 
#define NUM_PPP                         1      /* Max PPP sessions. */

#ifndef PAP_SUPPORT
#define PAP_SUPPORT                     0      /* Set for PAP. */
#endif

#ifndef CHAP_SUPPORT
#define CHAP_SUPPORT                    0      /* Set for CHAP. */
