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

Bought to set up Cisco equipment with my laptop. My laptop is running Fedora 16 (Kernel 3.2). While the description says this is supported on Linux, support appears to be very limited. Only kernel 2.4 or 2.6 are supported. The drivers on the CD didn't work either. The makefile contains references to init that were not used in several versions (the current version uses systemd). The readme file states that the drivers have been tested with Red Hat 9.0 and Fedora 2-7. If you're using one of the latest versions of Linux, you'll need to look elsewhere.
