single PCIe expansion slot. With the included break-out cable, you can easily add two ports to a single low

legacy serial devices to PCIe enabled computers.

standard and small form factor computers, and is compatible with a broad range of operating systems, including
Windows® 7/Server 2008 R2, 2003/Vista/XP (32 and 64 bit), Linux Kernel 2.6.11 and up, as well as MAC OS
