termios(4) says: "The CCTS_OFLOW (CRTSCTS) flag is currently unused." Yet code in /usr/src/sys/dev/uart/uart_tty.c references CCTS_OFLOW and as far as I know, it works. Hasn't it worked forever? Fix: Proposed replacement text: If CCTS_OFLOW (CRTSCTS) is set, transmission is stopped when CTS is lowered and resumed when CTS is raised. Maybe similar treatment is warranted for CRTS_IFLOW?
