getch: read a character in raw mode and write it and a newline to stdout.
If the input is a tty, it is put in raw mode to read a single character.
Usage: getch [ecp]
e: don't disable echoing of characters typed to tty.
c: get & write characters until stopped by signal or end of input.
In this mode, getch will terminate if sent an interrupt, quit, or
terminate signal, or if input ends. If the input is a tty, getch
will terminate if the EOF character is read. Also, getch can be
stopped by a broken pipe signal, which will be delivered if getch
is writing to a pipe and the output of the pipe is closed.
p: print a line giving the process id. This can be used to kill
getch without it reading & writing another character.
