From what I can tell,
The serial port is open, the buffer is read by the code below. I hope this Helps.
private byte[] readSerialPort(int readTimeout, System.IO.Ports.SerialPort portName)
{
byte[] buff = new byte[1];
//serialport.DiscardInBuffer(); // Clear the Recieve Buffer
serialport.ReadTimeout = readTimeout;
int readCount = 1; // Keep track of if we have to read again.
Char[] magic=new char[8];
ArrayList entireBuffer = new ArrayList(); // Use this arraylist to store the bytes for now.
delay(50); //give some time for port to have data
while (portName.BytesToRead > 0)
{
//200 not enough time to read serial port make a little larger
//there has been times when this was on the critical limit of reading the serial port
delay(400);
byte[] buffer = new byte[portName.BytesToRead];
//danger bad code dm200707
//int resultOfRead = portName.Read(buffer, 0, portName.BytesToRead);
//end danger bad code
//use this code -next line- to avoid race condition of buffer size available growing
int resultOfRead = portName.Read(buffer, 0, buffer.Length);
for (int i = 0; i < buffer.Length; i++)
{
entireBuffer.Add(buffer[i]);
}
readCount++;
}
// Create the byte [] to pass back.
try
{
buff = (byte[])entireBuffer.ToArray(typeof(byte)); // Export our arraylist into a byte array.
}
catch (Exception e)
{
MessageBox.Show("Couldn't Convert byte [] in readSerialPort()\n" + e.Message);
}
//-----------------------------------------LFLFLFLFLFLFLFLFLFLFLFLFLFLFLF--------------------------------
//-------------LF data is storage from here BN
//-------------------If COM2 take this
if(this.currentSerialPort == this.serialport1) //LF
{
delay(200);
for (int j = 0; j < buff.Length; j++)
{
if (j < buff.Length - 12) //so we dont go out of bounds of aRRAY IN OURT CHECK
{
if (buff[j] == (char)0x49) //make it faster by checking for this char first before all the others at once as well
{
if ((buff[j + 1] == (char)0x44) & (buff[j + 2] == (char)0x45) & (buff[j + 3] == (char)0x3D))
{
//if ((tranponderBytes[_keyNumber] != masterTranponderByte[_keyNumber]) && (rpt1 <= 100))
buff = new byte[]{buff[j+4],buff[j+5],buff[j+6],buff[j+7],buff[j+8],buff[j+9],buff[j+10],buff[j+11]};
return buff;
}
}
}
}
}
return buff;
}
