DB-9 Hardware Handshaking (RTS/CTS) Cable

The following cable is often sufficient for a terminal, printer, or other DTE device configured for RTS/CTS (hardware) flow control. However, some terminals and printers may have other cable requirements. Consult your terminal or printer manual for this information. For more universal compatibility, use a fully-wired DB-9 terminal/printer cable.
