Review on 🔌 Syba 2x Serial RS-232 RS-422 RS-485 DB9 Ports ExpressCard - Reliable Data Transfer & Connectivity by Ricky Mills

This review refers to "Syba 2x Serial RS232 Ports 34mm ExpressCard SD-EXP15010". I needed to log activity from two serial ports simultaneously at high speed on a Win7 x64 laptop. Using a dual port USB serial adapter (probably based on FTDI) resulted in a blue screen after just a few minutes. This Cardbus-based adapter worked without any problems. worth 25 dollars. The adapter is also said to support Linux, but I haven't had a chance or need to test this.
