here's wat i have done

Qt Code :

Qt Code: 
  1. int size;
  2.     int *i,j,k;
  3.     QFile file("/sfiles/mxdrv.tgz");
  4.     if(!file.open( IO_ReadOnly ))
  5.     {
  6.     	QMessageBox::information(0,"Error","Error opening file");
  7.     }
  8.     else
  9.     {
  10.     	cout<<"File opened successfully"<<endl;
  11.     }
  12.     cout<<"file opened...."<<endl;
  13.     unsigned char fname[]="mxdrv.tgz";
  14.  
  15.   struct termios t;
  16.   char *device = "/dev/ttyS0";
  17.  
  18.   int sPort, rbyte, status, sPortdest,length;
  19.   long count=0;
  20.  
  21.   unsigned char  send1[32];
  22.  
  23.  
  24.   t.c_cc[VMIN] = 1;
  25.   t.c_cc[VTIME]=0;
  26.   t.c_cc[VEOF]='\n';
  27.  
  28.   t.c_iflag |= (ISIG);
  29.   t.c_iflag &= ~BRKINT;	
  30.   t.c_cflag = B9600 | CS8 | CREAD | CLOCAL | HUPCL;
  31.  
  32.   sPort = open(device,O_RDWR|O_NOCTTY|O_NDELAY);
  33.  
  34.   	if(sPort != -1)
  35. 	{
  36. 		cout<<"open successfully\n";
  37.  
  38. 		status = ioctl(sPort,TCSETS,&t);
  39. 		cout<<"Entering status"<<status<<endl;
  40. 		if(status==0)
  41. 	      	{
  42.  
  43. 			//for(count=0;count<20;count++)
  44. 			cout<<"sending name"<<endl;
  45. 			rbyte=write(sPort,fname,strlen((char *)send1));
  46. 			//usleep(3000);
  47. 			cout<<"name sent"<<endl;
  48. 			cout<<"now sending file"<<endl;
  49. 			while(!file.atEnd())
  50.  
  51. 			{   
  52. 				//cout<<"Enter :";
  53. 				//cin>>send1;
  54.                                //strcat((char *)send1,"{MSS TYPE-D DAMA}");
  55. //	write(sPort,"{012345678}",11);	
  56. 				*i=file.getch();
  57. 				rbyte=write(sPort,i,sizeof(*i));
  58. 				cout<<rbyte<<"sent"<<endl;
  59. 				//cout<<"w b:"<<rbyte<<"\t Time:"<<count<<"\t string:"<<send1<<"\n";
  60. 				//usleep(1000);
  61.  
  62. 			}	
  63.  
  64. 		  }
  65. 		  close(sPort);
  66.  
  67. 	}
  68. 	else
  69. 	{
  70. 		cout<<"Device could not be opened";
  71. 	}
  72. 	file.close();
