Causing signals.

Hi: Please read this:
       Most process signals (not system signals SIGKILL, SIGSTOP, SIGCONT) are
       mapped to maskable interrupts. There are six  exceptions:  SIGTERM  and
       SIGHUP  will  terminate  z80-mon,  SIGABRT  will  set  the CPU-wait pin
       active, SIGUSR1 will cause a reset and SIGUSR2 will cause a NMI. Lastly
       SIGTRAP  will force the CPU immediately to dump its state into the file
       .CPU.  This enables online monitoring of the running CPU.
According to this, what signals could I use to cause a maskable interrupt and how do I produce the signal?

Pressing ^C I know I generate SIGINT. But the monitor program, the one whose manual I quote above, is executing a Z80 halt instruccion and then locks the keyboard. Any other means to generate SIGINT?

To get a list of signals, type on a command-line:
kill -l
kill may be used to generate any signal.
