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?
