I've used one on a Linux laptop, it "just worked" but the OS wasn't CentOS 7.
It is not clear if you used USB from APC UPS to USB port on the machine side or USB - to - "serial". USB to USB with standard USB cable will work.
If one uses serial to USB adapter on the machine side (to create serial port through USB on the machine), then one _has_to_use_ APC cable: as John Pierce just said, it is APC special cable which though has serial connectors on both sides of cable, (and uses serial protocol of communication - this is already what I am saying), it does not resemble neither serial nor null-modem cables.

Do not click links or open attachments unless you recognize the sender and know the content is safe. I need to connect an older APS UPS unit to a machine running CentOS 7. Unfortunately the UPS only has a serial port whereas the computer does not. I am aware that there are USB-serial adapters but that the hardware or the drivers might fall short of expectations. Does anyone have positive experience with such an adapter? Or, conversely, would recommend avoid a particular adapter? _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos Harriscomputer Leroy Tennison Network Information/Cyber Security Specialist E: leroy@xxxxxxxxxxxxxxxx [cid:Data-Voice-International-LOGO_aa3d1c6e-5cfb-451f-ba2c-af8059e69609.PNG] 2220 Bush Dr McKinney, Texas 75070 www.datavoiceint.com<http://www..com> This message has been sent on behalf of a company that is part of the Harris Operating Group of Constellation Software Inc.
