RTS (COM A / B)
If RTS/CTS handshaking is enabled, these LEDs illuminate when the CEN-COM is
ready to receive data from a serial device attached to the respective COM ports.

These LEDs illuminate when the serial device on the respective COM port is ready
to accept data from the CEN-COM. This “Clear to Send” signal is available only if
RTS/CTS handshaking is enabled; signal is controlled by external serial device. If
CTS signal is not connected (in cable), the signal is held high and the LEDs are
extinguished.
