Not really a compliant null modem cable. CD (pin 1) is wired straight through rather than being tied back to pin 6 (DSR). Does not work with file transfer programs that require handshaking. May work for some but total waste for me. Neither Amazon nor Startech provides any wiring diagrams (that I could readily find), had to manually buzz out.
Cable is long which helps when the device is in an obscure location. Works great.
