dear sir,
thank you for replying.In my project i just wanted to
send/recieve string by ppp connection.i have tried functions like
cyg_io_write(),sio_send(),sio_write() but nothing is working.when i
tried to implement these functions the ppp connection fails means that
in my code when i use these functions after the lwip_init(),& try for
ppp connection it fails to connect giving an error "set_cofig flow
control error".I am not able to understand why this error occurs even
if i use other functions after lwip_init()???please tell me what to
do?????
i have already asked this problem on ecos-discuss forum but no answers
yet so kindly answer to my problem.thank you

hello everyone,
i am using an ARM e7t kit on ecos.i have
established a ppp connection using lwip_init() between two
pc's(fedora) through ARM kit.i have made one pc as the server & the
kit as client.
my problem is that i am want to transfer data from one pc to another
through ARM kit.i have tried many functions.
Can someone suugest me a way to transfer a string from one pc to another.
here is my code:-
#include <cyg/infra/cyg_type.h>
#include <stdio.h> /* printf */
#include <string.h> /* strlen */
#include <cyg/kernel/kapi.h> /* All the kernel specific stuff */
#include <cyg/io/io.h> /* I/O functions */
#include <cyg/hal/hal_arch.h> /* CYGNUM_HAL_STACK_SIZE_TYPICAL */
#include "ppp.h"
#include "init.c"
/* DEFINES */
#define NTHREADS 1
#define STACKSIZE ( CYGNUM_HAL_STACK_SIZE_TYPICAL + 4096 )
/* STATICS */
static cyg_handle_t thread[NTHREADS];
static cyg_thread thread_obj[NTHREADS];
static char stack[NTHREADS][STACKSIZE];
/* FUNCTIONS */
void pppLinkStatusCallback(void * ctx, int errCode, void * arg) {
printf("entered call back\n");
}
static void simple_prog(CYG_ADDRESS data)
{
cyg_io_handle_t handle1;
Cyg_ErrNo err;
const char str[]="hi.i am shobhit\n";
cyg_uint32 len=strlen(str);
cyg_io_lookup( "/dev/ser0", &handle1);
printf("Starting serial example\n");
lwip_init(); //this function only is reponsible for the ppp
connection//
}
void cyg_user_start(void)
{
cyg_thread_create(4, simple_prog, (cyg_addrword_t) 0, "serial",
(void *)stack[0], STACKSIZE, &thread[0], &thread_obj[0]);
cyg_thread_resume(thread[0]);
}

Are you wanting to use a TCP/IP stack really? Or do you want to just send a
string through the serial port. If you want a TCP/IP stack, then you need
to make TCP/IP networking calls to create a new connection, and be running
PPP at both ends. If you want to just send a string out a serial port in
eCos, read the eCos serial driver documentation, which says to use
cyg_io_write(). If you have more questions on this, take them to the eCos
mailing lists: <http://ecos.sourceware.org/intouch.html> as this list is
for lwIP only.
