Selling a cash register that can be programmed with a PC via an RS-232 connection, but only needs to be connected to a laptop with USB ports. This Tera Grand cable worked great between the null modem cable I usually use and the PC. The bushings allowed me to twist the cables together to form a semi-permanent unit. This cable came with a mini driver CD, but Windows 10 automatically installed it before I could boot the CD. Communication is fast (for RS-232C) and transparent. I'm glad Revain is keeping the order history for me because I'll be buying more of these for other setups.
