Works great. I use it on a windows 10 64 bit PC for multiple ham radio interfaces. No driver problems at all.

This PCIe card was impossible to find drivers for. The complete lack of tech support was very disappointing. Will not be buying again.

Would not work with a new Dell desktop running win 10 pro. Errors on startup that could only be resolved by removing from the machine

Note that because this acts as a "legacy" port -- only 4 ports total are allowed. So an internal board port needs to be turned off to use all 4 ports on the device, which is best because they may be faster (at least 460800 baud) than local board port.Driver had to be loaded from SIIG website -- but actually worked! As opposed to multiple other boards which use a driver that does not work on Windows 11.

Worked perfectly, I'm using it in an automation solution and so far I'm having the expected result.

I'm one of those guys who, for his hobby, still needs lots and lots of RS-232 ports. Good cards like these are getting hard to find.Luckily, it's good to see that SIIG, a quality manufacturer I've had really good luck with in the past, still makes them!Installed in a brand new, Windows 10 PC. Loaded the drivers and 10 minutes later I was up and diddling away, both 45.45 and 75 baud RTTY, zero issues.Thanks, SIIG!
