Since my laptop does not have a serial interface, I bought such an adapter. The goal is an Embedded to hang via serial interface controller later on a simulation on the Linux laptop. I tested the data transfer first betw. 2 Laptops with 2 such adapters and the null modem cable of the same sender. The adapter is directly recognized by Linux and a fictional serial interface provided / dev / ttyUSB0 on Linux. For Windows a DriversCD is. Installation and testing on WinXP functioned without problems (provides COM3 and COM4 port ready). For the technicians: XP and Linux recognize the adapter as a Prolific 2303 chip.
A short USB cable is also attached so that the adapter is not down is directly related to its weight + socket part of a serial cable to the USB port of your laptop.
Super equipment at a great price and the operating systems Compatible -> 5 Stars.
