In reference to having a signal "when terminal input is available,"
this can be done.  The signal is (I believe) SIGTINT.  An appropriate
ioctl call is also in order.  The main restriction for this is that
the user must be using the "new" tty driver.

Although this can be done, I feel it is insufficient.  The main problem
is that signals (at least UN*X signals) are lousy to begin with.  For
example, repeated signals are lost if the signal is not reset quickly
enough.  Another problem is that a signal will cause a premature return
of a system call (except for file I/O)!

I guess if I were to create a UN*X wish list, it would definitely include
improved signals.
