Descrizione

https://github.com/dotnet/runtime/blob/dc0e11d2e681659fc20feebf4c092082e75706af/src/libraries/System.IO.Ports/src/System/IO/Ports/SerialStream.Unix.cs#L841

if you short read the available bytes, there is a 1ms delay between reads as all reads now go via an async process and queue eg port.BytesToRead > 4

port.ReadByte(); // 1ms port.ReadByte(); // 1ms port.ReadByte(); // 1ms port.ReadByte();
