Cannot catch SIGINT while serial break condition occurs
I setup termios structure with IGNBRK is not set and BRKINT is set.
To allow the process to receive signals I call: fcntl(fd, F_SETOWN, getpid());
I have made a signal handler to catch all signals. I can catch SIGINT when pressing ctrl+c but when I send break signal over serial then it cannot catch SIGINT.
Is there anything I'm doing wrong?
Any suggestions and code samples would be appreciated.
Thanks

For a program I am designing, which involves handling the keyboard input Ctrl^c (SIGINT), it is taking ages for the program to actually recognise and perform the corresponding action whenever I run it and hit Ctrl^C at the CL.

break
break(1T) Tcl Built-In Commands break(1T)
__________________________________________________________________________________________________________________________________________________
NAME
break - Abort looping command
SYNOPSIS
break
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which
causes a break exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command,
which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch com-
mand, Tk event bindings, and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 5:
for {set x 0} {$x<10} {incr x} {
if {$x > 5} {
break
}
puts "x is $x"
}
