Port.Read Timeout on a SerialPort #173
Comments

You have rewritten its settings here. |

OK, so those values are just a higher layer abstraction of the actual serial port values. That makes sense. |

The last value will win.
The line:
master.Transport.ReadTimeout = 1000
Just calls serialPort.ReadTimeout under the covers.

Good day,
I would like to understand how the library works with serial timeouts?
I have the following test code:
` var serialPort = new SerialPort("COM1", 9600, Parity.None, 8,
StopBits.One);
//Set Serial Timeouts
serialPort.ReadTimeout = 500;
serialPort.WriteTimeout = 100;
var factory = new ModbusFactory();
IModbusMaster master = factory.CreateRtuMaster(serialPort);
//Change settings
master.Transport.Retries = 0;
master.Transport.ReadTimeout = 1000;
master.Transport.WriteTimeout = 200;
//Read device which is offline.
master.ReadHoldingRegisters(1, 1, 1);`
Which timeout values will be applied to the actual physical rs485 serial
port?
A: 550 & 100
or
B: 1000 & 200
