16c95x Serial Port Driver Work Site
The is the software that allows your operating system (Windows 7, 10, or 11) to communicate with these PCIe or PCI cards. Without it, your computer cannot send or receive data through these ports, often causing devices to be listed as "Other devices" in the Device Manager. 1. How to Identify Your 16C95x Device
Installing a dedicated 16C95X driver unlocks the following features:
Many older 16C95x drivers are unsigned. You may need to "Disable Driver Signature Enforcement" in Windows Startup Settings to install legacy versions. Conclusion
The 16C95x (often referring to OX16C950, OX16C952, and OX16C954 chips originally developed by Oxford Semiconductor and now managed by companies like Exar/MaxLinear) is a line of . These chips are frequently found on multi-port serial cards produced by manufacturers like StarTech.com, Sunix, and SIIG. 16c95x serial port driver

The 16C95X serial port driver remains a cornerstone for high-speed, reliable serial communications across industrial environments. By ensuring you have the correct vendor-specific driver installed and properly configuring your FIFO buffers, you can maintain seamless backward compatibility for legacy software while enjoying modern, hardware-accelerated data transfer speeds.

If you are running Linux, you rarely need to download a third-party driver file. The Linux kernel features native, highly optimized support for the 16C95X architecture embedded directly within the core serial subsystem ( drivers/tty/serial/8250/ ).

Great article, lots of steps but worked like a charm. CF 9 is the last version I have, but I recently upgraded servers to Windows 2016 Server and didn’t want to upgrade CF at the huge cost for the small website I maintain. Still trying to get other websites to work other than the default, but I’ll get through that now that CF is working.
Hi Tom
Glad to hear things worked well. Enjoy and Cheers
Tom
This is a really good tip particularly to those new to the blogosphere.
Simple but very precise information… Thanks for sharing this one.
A must read article!
Up graded the server to 2016, the reinstall worked like a charm, lots of information, obviously lots of time and work put into this. Thank you very much for sharing.
The JWildCardHandler wildcard broke the regular sites so I removed that handler and so far everything is working fine for me anyhow.
Didn’t want to update from CF 9 could not justify the expense for 2 websites we serve.
Thanks again for a great how-to post!
Tom, this is indeed a very helpful breakdown. (There are still other ways to make things work, but I’m sure many will be satisfied with this alone.)
That said, and while you mention security a few times, it really should be emphasized very strongly to people doing this: beware that you’re using a version of CF that is 9 years old! (as of this writing): since then we have CF10, 11, 2016, and 2018, all of which have had major security enhancements (and of course many other enhancements).
Keep in mind that CF9 stopped being updated in 2013. There have been no more public bug fixes–or security updates to it–since then. That said, some good news is that some of the security improvements in 10 were actually also made available as security hotfixes for 9 (and even 8 back then), so at least having those updates in place would be better than running a stock 9 install.
But many people find that they have never have applied any CF9 updates, let alone security updates.
I have many blog posts about CF9 updates, and I did one that pulls all the info together (including tools and other resources), which may help some readers in that boat:
http://www.carehart.org/blog/client/index.cfm/2014/3/14/cf9_and_earlier_hotfix_guide
I can also help people with doing such updates, if interested. Though again I always warn folks that this is a bit like putting lipstick on a pig.
And I’m simply warning folks here that trying to force CF9 to work on Windows 2016 (or 2012) is basically playing with a loaded gun. You’re updating the OS because you want to/feel you have to but you are not updating CF (perhaps because it will cost money or you fear compatibility issues, or whatever).
Maybe the better analogy is that it’s a WW2 era gun. You might be able to get it cheaper, or it’s just “what you know” and prefer to use, and you MIGHT take really good care of it, but just beware that if not taken care of it may well explode in your face. So be careful out there.
You are God send…. CF9 works now on Windows 2012
Following your guide, with minor adjustments, I was able to get ColdFusion 9 to run on Windows Server 2019! My only problem is now ASP.net sites serve up “404 – File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.” errors. I moved the five Handler Mappings “Script Map” down from the top level to a specific CF9 site thinking it would help the ASP.net site. The CF9 site runs beautifully yet the change didn’t help my ASP.net situation. I’m hopeful someone can provide insight into what may have caused this problem and how to fix it.
Hi Rick
> My only problem is now ASP.net sites serve up “404 – File or directory not found.
Did you remove all handler mappings as described?
Regards
Tom
I only added the handler mappings, left the others alone. Although the original ones fell below the fold post moving the custom Handler Mappings to the top of the Ordered List.
Try to move the Static Handler Mapping with the wildcard path (*) below the .asp or .aspx handler and probably play around with the 32-bit application pool setting “Set Enable 32-bit Applications”. Also check if you have a blocking rule at “Request Filtering” options within IIS. To be sure, execute a ‘iisreset’ command after your modifications and before you test.
I am looking at doing an inplace upgrade from 2008r2–>2012r2 with CF9 installed. Has anyone seen how this reacts?
I didn’t. Maybe you install a fresh server and then use the “Packaging&Deployment” functionality to migrate all your stuff over to the new server. Have a look at the CF Administrator at “Packaging&Deployment” -> “ColdFusion Archives”. I don’t know if this works. You probably try it on a testsystem first. I always installed fresh and did a manual migration.
Thanks for response! I was trying to avoid building out a new box as I will be retiring Cold Fusion (finally) in 2020.
I will give the upgrade path ago (2008r2–>2012–>2016) in my test environment and report back what craziness happens.
OK,
The in place upgrade from 2008r2–> 2012 r2 standard went well. I am working through Java.lan.NullPointerException 500 error with CF9 though. Keep you all posted.
Hello,
Just wanted to drop in and say that I successfully did an in-place upgrade of a 2008r2 box running CF9 and it went really well. Aside re-installing .net 4.7 our CF9 installation didn’t seem to mind. Good luck out people.
