site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Organization: Rogue Research Hi all, I notice that the highest speed termios.h defines is B230400. I have a serial device that supports higher speeds such as 921600. Is it not present in termios.h because it is unsupported? tcsetattr() returns success after setting the speed to 921600. Do the supported speeds depend exclusively on the serial hardware (USB-serial adapter these days)? Or does the OS have influence on which speeds are allowed? I ask all this because my device works at many speeds, except the highest speed it supposedly supports. I'm trying to figure out if this is the device's fault, the OS's, or the USB-Serial Adapter's. Thanks, PS: I hope this list is appropriate, sorry if not. -- ____________________________________________________________ Sean McBride, B.
