https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240121 --- Comment #2 from Alexander Motin <mav@FreeBSD.org> --- That effect is unexpected to me. I would expect opposite -- reduction of wait time, since code reduces number of buffer flushes and utilizes hardware FIFO. I may need to reproduce it to understand the issue. What UART hardware are you using? Does it have FIFO? -- You are receiving this mail because: You are the assignee for the bug.help
