Could you clarify if the problem was driver software damage or serial port number randomization on power up due to power on race conditions?</div>

The later is a continual problem with Windows and usually solved by repeated restarts (not power ups) which results in stable port numbers.</div>

<div>Tyler,</div>
<div><br>
</div>
<div>Thanks to find out. That’s exactly the issue I have with the computer department, which pushes partially updates in and claims it’s harmless. The fix was always ignored a year later.</div>
<div><br>
</div>
<div>Please please let me know when you finish the driver update.</div>
<div><br>
</div>
<div>Thanks,</div>

I repaired the NI-Serial driver and was able to at least see the RS-485 and RS-232 converters on the PC. I am now updating the NI-Serial driver to see if that fixes everything.</div>

I remember in the past that this has happened before when the PC reboots or is updated. A similar situation probably happened in this instance.</div>
