ポート固定/FTDIチップ使用のUSBシリアル変換ケーブル
仕事でいまだにRS-232な環境があるため、ノートパソコンにUSBシリアル変換をつなげて使用してきました。この製品はFTDIのチップ(おそらくFT232R)が使用されており、さらにあらかじめシリアルナンバが書き込まれているため、違うUSBポートに差してもCOMポートが無駄に増殖することはなく同じCOMポート番号で使用できるので快適に使用できます。また、ボーレートに関しても看板に偽りなく921600bpsでも波形がなまらずきっちり出ます。仕事で安心して使える逸品です!

El que mejor funciona
Es el mejor adaptador USB a RS-232. He probado varios, y todos dan bastantes problemas. Por ahora es el mejor de los que he probado.
