Using the mainline's uartlite driver, is it possible to break (CTRL+C)? When I run ping, for example, I cannot quit using CTRL+C as PuTTY will only show "^C" and the kernel doesn't do anything. I noticed this into the driver:
static void ulite_break_ctl(struct uart_port *port, int ctl)
{
/* N/A */
}
Does that mean there's absolutely no way it's going to work? Setting or not brkint using stty doesn't change anything.
Also, see my SO post: http://stackoverflow.com/questions/10467687/why-ctrlc-wont-work-when-using-rs-232-on-linux.
Hope someone can clarify this for everybody!
