Notes: This table is only intended as an example. It does not provide the RTS-CTS
delay for all available port speeds.
The RTS-CTS delay added by RTS-DCD Simulation is in addition to the RTS-CTS delay
selected by the Port CTS Delay parameter described on page 5-13. It is possible to see
the DCD drop code at the DTE interface per CCITT Recommendation V.13
V.13 RTS-DCD Simulation is not supported when the port is configured for
asynchronous operation.
