### RJ-45 8-Pin Plug Hardware Handshaking (Ready/Busy) Cable

Using an 8-pin plug, the following cable wiring is often sufficient for a terminal, printer, or other DTE device configured for DTR (hardware) flow control. However, some terminals and printers may use a signal other than DTR for flow control. In addition, some terminals and printers may have other cable requirements. Consult your terminal or printer manual for this information.
