After using a number of serial-port-components, I've got the best results until now, by using CreateFile('\\?\COM1',GENERIC_READ or GENERIC_WRITE,0,nil,OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,0), passing that handle to a THandleStream instance, and starting a dedicated thread to read from it. I know threads take a little more work than writing an event handler, but it still is the best way to handle any synchronization issues that arise from using serial ports.
