Displaying serial data to screen

[Deveau, Darrin]

Hi, 

I want to use Windows Hyperterminal to send a text file to the palm and to
display the text on the palm.  This is for testing purposes.

The Text file is like follows: 

16534567 
16534567 
16534567 
16534567 
16534567 

I send the file and what I get display on the Palm is the number of bytes in
the buffer.  This is correct, but I want to display each character received.

What I get is the following: 

1^{[]6,  etc...  

What I want to see is what is in the text file above. 

16534567 
16534567 
16534567 
16534567 

Any suggestions? 

Thanks, 
Darrin 

Here is the ReceiveTerminal code: 

void ReceiveTerminal (void) 
{ 
   char szBuf[1024]; 
   static int index = 0; 
   Err error; 
   ULong ulBytes; 
   int increment1, i; 
   CharPtr sA, sX, cStatus, sBytes, sBuffer; 
   long timeout; 
  
   increment = 0; 
   increment1 = 0; 
                
   if (Connected == 0) return; 
        timeout = SysTicksPerSecond() / 2; 
                
   error = SerReceiveWait(gSerialRefNum, sizeof(szBuf) - 1, timeout); 
    
   if (error == serErrLineErr) 
   { 
       FrmAlert(RS232LineErrorAlert); 
       SerReceiveFlush(gSerialRefNum,100); 
       index = 0; 
       return; 
   } 
   if (error == serErrTimeOut) 
   { 
        FrmAlert(InterbyteTimeoutAlert); 
        SerReceiveFlush(gSerialRefNum,100); 
        index = 0; 
        return; 
   } 
        
   error = SerReceiveCheck(gSerialRefNum, &ulBytes); 
   
   // display number of bytes in buffer to screen 
   StrIToA(sBytes, (int)ulBytes); 
   sBuffer = "Buffer"; 
   WinDrawChars(sBuffer, StrLen(sBuffer), 30,146); 
   WinDrawChars(sBytes, StrLen(sBytes), 60, 146); 

    if (error == serErrLineErr) 
    { 
        FrmAlert(RS232LineErrorAlert); 
        SerReceiveFlush(gSerialRefNum,100); 
        index = 0; 
        return; 
    } 
    if (error == serErrTimeOut) 
    { 
        FrmAlert(InterbyteTimeoutAlert); 
        SerReceiveFlush(gSerialRefNum,100); 
        index = 0; 
        return; 
    } 

    do 
    {   
        SerReceive(gSerialRefNum,&szBuf[index] - 1,1,0,&error); 

        if (error == serErrLineErr) 
        { 
            FrmAlert(RS232LineErrorAlert); 
            SerReceiveFlush(gSerialRefNum,100); 
            index = 0; 
            return; 
        } 
        if (error == serErrTimeOut) 
        { 
            FrmAlert(InterbyteTimeoutAlert); 
            SerReceiveFlush(gSerialRefNum,100); 
            index = 0; 
            return; 
        } 
        
        sX = &szBuf[index]; 

        //Draw chars until screen line full, then move down a line 
        //Draw 8 lines before overwritting first line 
          
        WinDrawChars(sX, StrLen(sX), 5 + increment1, 70 + increment); 
    
        increment1 = increment1 + 10; 
        if (increment1>130) 
        { 
            increment1 = 0; 
            increment = increment + 10; 
        } 
        if (increment>60) 
        { 
            increment = 0; 
        } 
    
        index++; 
        ulBytes--; 
     } while (ulBytes); 
}
