It looks like they're changing over to rtsxoff and ctsxon, but these options aren't enabled in stty yet, and the man pages for stty and termio haven't been updated. Look at man asyc for other options to open the serial port with certain modes already enabled, by using devices in /dev/tty* and /dev/term: # l /dev/tty1[aA] crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/tty1A crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/tty1a # l /dev/tty00* crw-rw-rw- 1 bin bin 3, 0 Jul 21 06:51 /dev/tty00 crw-rw-rw- 1 root root 3, 1 Aug 30 12:03 /dev/tty00h crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/tty00m crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/tty00s crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/tty00t # l /dev/term/00* crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/term/00 crw-rw-rw- 1 root root 3, 1 Aug 30 12:03 /dev/term/00h crw-rw-rw- 1 root root 3, 3 Aug 30 12:03 /dev/term/00m crw-rw-rw- 1 root root 3, 0 Aug 30 12:03 /dev/term/00s crw-rw-rw- 1 root root 3, 2 Aug 30 12:03 /dev/term/00t So, /dev/term/00t and /dev/tty00t are the equivalent of /dev/tty1a (terminal), and /dev/term/00m and /dev/tty00m are the equivalent of /dev/tty1A (modem). /dev/term/00h and /dev/tty00h have RTS/CTS (hardware) handshaking enabled. (This is the one you're looking for.) /dev/term/00, /dev/term/00s, /dev/tty00 and /dev/tty00s have XON/XOFF (software) flow-control enabled. Bob
