The file /dev/tty is, in each process, a synonym for the control
terminal associated with the process group of that process, if any.
It is useful for programs or shell sequences that need to be sure of
writing messages on the terminal no matter how output has been
redirected. It can also be used for programs that demand the name of
a file for output, when typed output is desired and it is tiresome to
find out what terminal is currently in use.
You can use /dev/tty from any type of terminal to refer to the current
terminal; it should work the same way from a console or an xterm.

Well, if your program was running in the background at the same time
mutt was running in the foreground, then you would have trouble reading
from the tty. When I've done that inadvertently, each program seems to
get about half the keystrokes, every other keystroke going to a
different program. Otherwise, as long as mutt is suspended waiting for
your program to finish before it continues, you should be able to
redirect your program's stdin from the tty without any problem.
Maybe if you could provide more details of exactly what you did and
exactly how it failed, we might be able to figure out a solution.
