I'm in trouble with POSIX signals.
¿Are POSIX signals delivered in the ASR POSIX routine?
I mean, I try to send a signal from one thread to another,
but 'cyg_posix_signal_asr' function is called from
the signal origin thread after calling 'kill(other thread,SIGNAL)',
but this call is not done from any ASR routine.
¿How are POSIX signals delivered from one thread to another ?

Fdo.

You mean pthread_kill() surely? If you use kill() then that sends a signal
to the whole process (and in eCos there is only one process), not just one
thread. Therefore any thread can receive it (unless explicitly masked).
