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.
