Hello, Noticed that serial port RTS does not drop inactive when a sio-device is closed. DTR does drop. I suppose the hupcl 'modem disconnect' operation does not necessarily require RTS to drop, still, isn't it a bit silly to leave RTS high when DTR goes low in this case ? This omission might be intentional, fine then. Also noticed there were issues with DTR getting overwritten whenever line is reconfigured (comparam()). This will not bite if the termios are set initially by a program and then only reads, writes and TIOCMBIC/BIS are used, by this single program only ? (meaning, no spontaneous comparams happen ? (console is elsewhere)) Thanks, Juha To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
