Hardware Flow Control
If this feature is enabled, the engine determines whether to transmit data based on CTS signal level.
When CTS signal is at low level which
means the serial port’s cache memory of receiving device (such as
PC) is full, the engine will not send data through serial port until CTS signal is set to high level by receiving
device. When the engine is not ready for receiving, it will set RTS signal to low level. When sending device
(such as PC) detects it, it will not send data to the engine any more to prevent data loss.
If this feature is disabled, reception/transmission of serial data will not be influenced by RTS/CTS signal.
Enable Hardware Flow Control ** Disable Hardware Flow Control
Note: Before enabling this feature, make sure that RTS/CTS signal line is contained in RS-232 cable.
Without the signal line, serial communication errors will occur.
