How is your RS-485 driver connected to your ESP8266? It sounds like you are having an echo problem, where you are receiving everything you are sending. Connecting the RE and...

The MAX3485 definitely requires a control pin.  *Image source: [MAX3483-MAX3491 datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/max3483-max3491.pdf)* My understanding is that additional circuitry can be used to automatically manage the `DE` and `RE`...

You are free to make any tweaks you want. I don't plan on incorporating these changes into the library. That module seems a bit sketchy to me. I couldn't find...

Huh, In whatever core you are using, it looks like they changed the serial configuration (like `SERIAL_8N1`) to be of type `SerialConfig` rather than an integer type. What core/board are...

You could run something like this before running `modbus.readHoldingRegisters`. ``` C++ while (mySerial.available()) { mySerial.read(); } ``` This should clear `mySerial`'s receiving buffer.
