[ECOS] e7t write problem

[Vinayak P Risbud]

   Hi,

        I am working on ARM e7t board.
        My problem is,  I am not able write my data
        on other serial port (i.e other than com port)

        My code is like this :

        int len, msglen;
        char msg[] = "This is a test \n";

           err = cyg_io_lookup("/dev/ser0", &handle);
          if (err == ENOERR){
               diag_printf("We got the handle \n");
               diag_printf(" Handle %d \n", handle);
          }
         else{
       diag_printf("opening port failed \n");
       return;
      }
      len = sizeof(serial_info);
      err = cyg_io_get_config(handle,  CYG_IO_GET_CONFIG_SERIAL_INFO,
&serial_info, &len);
      if (err != ENOERR)
      {
       diag_printf(" cant get serial config \n");
       return;
      }
  diag_printf("Baud: %d, stop: %d, parity: %d \n", serial_info.baud,
serial_info.stop,
serial_info.parity);

 len = sizeof(serial_info);
 err = cyg_io_set_config(handle, CYG_IO_SET_CONFIG_SERIAL_INFO,
&serial_info,
&len);
 diag_printf("set config error %d \n", err);
 msglen = strlen(msg);
 err = cyg_io_write(handle, msg, &msglen);
 diag_printf(" write error %d \n", err);
 if (err != ENOERR)
 {
  diag_printf(" cant write data %d \n", err);
  return;
 }

The output is

    We got the handle
    Handle 135472
   Baud: 18, stop: 1, parity: 0
   set config error 0
   write error 0
--------------------------------

   I have connected the e7t other port to PC's COM2 on a straight RS232
cable.
   minicom on COM2 does not show any bytes receved

    Any one helps me in fixing this problem ?

    thanks and regards
            Vinayak
