commit 671c393854a5ae60369beadfb74007e240bb18ab Author: Hans Petter Selasky <[email protected]> AuthorDate: 2021-01-07 14:34:26 +0000 Commit: Hans Petter Selasky <[email protected]> CommitDate: 2021-02-01 09:31:58 +0000 MFC ea0efc370416: Add support for PL2303HXN to uplcom(4). Code changes in this commit were obtained from straight from OpenBSD's uplcom.c with almost no modification, the list of chip names and USB IDs was obtained from Linux.
