The way RS-232 (and all the other specs I've read) work is that the DTE raises RTS and if the DCE is able to accect data, it raises CTS in response. When the DCE can't accept more data, it drops CTS. That sounds like RTS/CTS flow control to me. If they do something differently, it's proprietary. > -Ron -tony
