The turn around delay allows for 0.4 seconds for the Modbus slave to respond. On low baudrate serial connections, a single request (such as write multiple registers) might exceed the 0.4 seconds.
Add a time delay that estimates how long to wait before timing out based on the write packet size and baudrate
