I've used one on a Linux laptop, it "just worked" but the OS wasn't CentOS 7. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of H <agents at meddatainc.com> Sent: Wednesday, July 8, 2020 10:13 AM To: Centos Mailing List <centos at centos.org> Subject: [EXTERNAL] [CentOS] USB-serial adapter for CentOS 7 CAUTION: This email originated from outside of the organization. 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 at centos.org https://lists.centos.org/mailman/listinfo/centos Harriscomputer Leroy Tennison Network Information/Cyber Security Specialist E: leroy at datavoiceint.com [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.
