Simple usage of serial cserialport

Simple usage:

1. Define members:
Cserialport m_serialport;

2. Initialization:
M_serialport.setbuffersize );
M_serialport.setwnd (m_hwnd );
M_serialport.setpolicynum (def_in_byte_size );
If (m_serialport.isopen ())
{
M_serialport.close ();
}
M_serialport.open (1, "9600, O, 8, 1 ");

M_serialport.clearinputbuffer ();
M_serialport.clearoutputbuffer ();

3. receive data:
A. on_message (on_com_receive, rs232onreceive)

B. rs232onreceive function body:
} M_serialport.lock ();

Byte _ rxdata_array [def_in_byte_size];
Zeromemory (_ rxdata_array, def_in_byte_size );
Int nreceivedlength = 0;

Byte tempbyte [def_in_byte_size];
Zeromemory (tempbyte, def_in_byte_size );
Int _ bufferlength = 0;

// Bool bfound0x51 = false; // indicates whether the data header has arrived.
DWORD _ tickcount = gettickcount ();
While (nreceivedlength <def_in_byte_size)
{
If (gettickcount ()-_ tickcount)> 50) // prevents endless loops that cannot receive data
{
Trace ("receiving data timeout. \ n ");
Break;
 

_ Bufferlength = m_serialport.read (tempbyte, 1 );
// If (! Bfound0x51) // if no data header is obtained
//{
// If (tempbyte [0] = 0x51) // determines whether the data header has arrived
//{
// Bfound0x51 = true;
//}
//}
//
// If (! Bfound0x51)
//{
// Trace ("0x % 02x: Wait for the data header to arrive. \ n", tempbyte [0]);
// Continue;
//}

If (_ bufferlength> 0)
{
Memcpy (_ rxdata_array + nreceivedlength, tempbyte, _ bufferlength );
Nreceivedlength + = _ bufferlength;
}
}

M_serialport.clearinputbuffer ();
M_serialport.unlock ();

4. Send data:
M_serialport.lock ();
M_serialport.write (txbuffer, 9 );
M_serialport.unlock ();
