Only one byte is read when reading just now opened SerialPort

Question

Strange issue.

When I read from com-port with SerialPort.Read(), then if data arrive, only one byte is read on the first call, disregards of count

Answer 1

I've found my solution I hpe this helps:

ireadCount = serialPort.Read(readBuffer, 0, serialPort.ReadBufferSize);
Thread.Sleep(1);//This can be removed, just use it in case need time to complete the reception.
ireadCount = serialPort.Read(readBuffer, 1, serialPort.ReadBufferSize-1);
ireadCount +=1;

This way I can have the whole response from the external device without losing the first byte.

Regards.-
