Hardware Auto Flow Control
When enabled，HR200 will decide if the data should be sent in accordance with CTS signal level. When it
is low level CTS signal, it means the serial port's cache memory of receiving end (such as PC) is full and
HR200 will not send data through RS232 until CTS signal is set to high level by receiving end.
When HR200 is not ready for receiving, it will set RTS signal to low level. When sending end (such as PC)
detects it, it could not send data to HR200 any more, otherwise the data will be lost.
When disabled, data's sending and receiving through serial port will not be effected by RTS/CTS signal.
**Disable Hardware Auto Flow Control

Before enabling this function, please be sure that RTS/CTS signal line is contained in RS232
cable. If not, a RS232 communication error will occur.
