I haven't had CTRL-\ do anything ctrl-C doesn't this decade, but I'll take your
word for it.
I think this would need to be implemented in the kernel. The tcsetattr page says:
(not in POSIX; not supported under Linux; status request: 024,
DC4, Ctrl-T). Status character (STATUS). Display status infor‐
mation at terminal, including state of foreground process and
amount of CPU time it has consumed. Also sends a SIGINFO signal
(not supported on Linux) to the foreground process group.
But the "not implemented" part is kind of a downer. Three's no SIGINFO in
asm-generic/signal.h and they've used all 32 bits (for crazy things like SIGXFSZ
which for some reason isn't the same as -ENOSPC?)
*shrug* I got asked, thought I'd look into it...
