Please quote messages. Most people won't have the time or patience to go back and see that this is a question about a 25xx (can't remember exactly) serial interface that is up/up despite RTS being down. The encapsulation is Frame Relay, if I recall.

Does it mean > that we can ignore RTS signal? RTS should be asserted by the DTE side along with DTR. But it's possible RTS doesn't really matter if the other ones are up. Have you tried a different cable? Have you tried a different serial interface? Do you still get the same results? What version of IOS is it? The only real discussion I could find on CCO about RTS being down had to do with low-speed, half-duplex serial lines. It seems to matter then. Otherwise, maybe it doesn't??
