Description

Could be that the RTU answers properly but after the timeout, which means that the binding's next read reads the answer which was late and is waiting in the device's read buffer.

Fix which flushes input buffer before sending a request after a time out: any possible late answer is discarded before sending a new request

Please note that the timeout value of this device should still be increased to avoid errors
