Good pinout for data transfers
Works well for file transfers between old computers via HyperTerminal or other terminal software.

Great cable, saved my bacon!
I used this in conjunction with Norton Commander for DOS to back up data from a vintage PC that didn't have a working disk drive. It worked great and got me out of a pinch!

Worked like a Charm!
This cable worked awesome to connect Digi SP One from car wash Server to a remote Digi for communication. Tried different same type cables and did not work!

Great Cables
Thermoking HVAC controller on CAF LRV use null cables for interface. The M-F and F-F cables made easy to verify performance without having to use a laptop perched on top of a kadder.

Un producto simple y bien hecho, como debería de ser todo.
Necesitaba un cable serie (parece mentira que hoy en dia, todavia se necesiten cables de comunicaciones RS232) para la instalación de unos equipos y lo compré esperando que fuera un objeto con una calidad justa pero nada mas de mi opinión inicial. Me encontré un objeto muy bien terminado y de calidad (ya habia probado otros cables de 3metros de longitud y daban problemas a menos velocidad - lo tenia que usar a 115200bps, 8,1,N). Voalvería a comprar otro en caso de ser necesario? Sin duda.

A good 9-pin null-modem serial lead
I used this to connect an FTDI USB to serial converter to an APU4 router, but it would work anywhere you need a standard null-modem cable, i.e. connecting two DTEs (computers, etc.). I would have made up my own cables for this in the past, but there doesn't seem much point at this price.

Yamahaのルーター設定用として
Yamahaのルーター設定のためにクロスケーブルが必要だったので購入。 昔はモデムの設定をしたりとRS-232cは必須のケーブルだったのだけど、今はもうパソコン側にもRS-232C端子が付いていないぐらい無くなってしまった。 どこかにあったはずなのだがアナログ回線の終了と共に処分してしまったのかもしれない。 しかし、現代では注文すれば翌日に到着なので非常に便利。おかげでルーターの設定もできました。
