Serial Port Demons

And it's random, so if you boot and there happens to be no data coming in port at the time of initialization the system starts normally and the CQC driver serial port assignment(s) work correctly. However if you are really lucky then the undesirable assignment occurs and boom the driver doesn't work since it can't obtain it's assigned serial port.

I'm thinking about trying a delayed start on the serial port device service and CQC to see if I can trick Windows to not do the undesirable assignment.  

Dean, which service(s) would I need to delay along with the serial port service to test this theory out?

BTW this is a brand new system with performance room to spare, it's probably too damn fast.

I'm also considering a different serial input method, like a multi-port card (I need 7) but they are big $$$ for anything of quality.

I have used Digi Edgeport usb to serial boxes without fail on my win 8.1 machine and would highly recommend them. They have an 8 port unit that would suffice. I purchased used on ebay (one is currently listed for $30).

Not yet, work / life interfered, hope to get back to it this weekend.

Interesting, thanks for sharing, I'll take a look at that.

Well this was a bust. Sad   I don't have anything I can delay on startup with regard to the serial port driver.  Exploring other hardware options.
