DTE-A is receiving data and its receive FIFO threshold is reached, the RTS signal goes
in-active ’HIGH’ forcing the CTS of DTE-B to become in-active indicating that
transmission has to stop after finishing the current character. Both DTE devices should
also be using the CTS signal to flow control their transmitters. When the shadow receive
FIFO in DTE-A is cleared its RTS goes active (low) and this signals the far end DTE-B
to resume transmission. Data flow control from DTE-B to DTE-A works in the same way.
