Serial Port Port.Write() Command

I'm curious as to why when I use the SerialPort.Write() command, the command I'm trying to send doesn't actually ever get sent. (Maybe it just sits in the buffer, or is just saved somewhere, I don't know). I have to use the SerialPort.BaseStream.BeginWrite() command to actually physically send that command. Why is that?

Thanks,

The BeginWrite method on a stream calls the Write method synchronously, which means that Write method might block on some streams. To determine whether the current instance supports writing, use the CanWrite property.
