[ECOS] problem on second serial e7t

[Katerina Malatara]

Hi,
I have written this code and i notice something strange.

/* INCLUDES */

#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 */

/* 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 */
static void simple_prog(CYG_ADDRESS data)
{
	cyg_io_handle_t handle1, handle2;
	Cyg_ErrNo err1, err2, err3;
	char buffer[100];
	cyg_uint32 len = strlen(buffer);
	char line[] = "It is working!!!!\n";
	cyg_uint32 len1 = strlen(line);
	FILE *ptr1;
	FILE *ptr2;

	printf("Starting serial example\n");
	err1 = cyg_io_lookup( "/dev/ser0", &handle1 );	// user port
	err2 = cyg_io_lookup( "/dev/ser1", &handle2 );	// debug port
	if (err1==ENOERR)
		printf("Found /dev/ser0.\n");
	if (ENOERR == err2)
		printf("Found /dev/ser1.\n");
	ptr1 = fopen("/dev/ser0","r");
	printf("Send the data...\n");
	fscanf(ptr1,"%s",&buffer);
	printf("The buffer has: %s\n",buffer);
	cyg_io_write(handle1,line,&len1);
	err3 = cyg_io_write(handle1,buffer,&len);
	if (ENOERR == err3)
		printf("the write function is working!!!\n");
	fclose(ptr1);
}
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]);
}

i have connect ttyS1 with minicom. I write  in minicom "katerina" the buffer 
has the string katerina but then it is not printing in minicom like the 
string in char line[] = "It is working!!!!\n"

the output of gdb 

Starting serial example
Found /dev/ser0.
Found /dev/ser1.
Send the data...
The buffer has: katerina
the write function is working!!!

the output of minicom 

katerina
It is working!!!!

if someone has any suggetions i will be very happy
Thanks for your help
