I am very new in Expect/k. I tried to automate a program which takes
stdin and have user interaction thru /dev/tty and outputs to stdout
with Expect/k which I assume it can take the job.

Diagrammatically,

stdin -------> Program A -------> stdout
                ^
                | user interaction
/dev/tty -------

is wrapped by the Expect/k script to make sth like

stdin ------->       Expect/k script to -------> stdout
                automate the user
                interaction

Can it be done and how? I tried but I can't redirect the stdin of the
script to the program A, program A waits there indefinitely....

Email is most welcome.

Thanks.
Andrew
