It will give you "ports" for stdin/stdout. e.g. (example to ssh to a
server, start a process and interact with it):
(let-values ([(recv-port send-port connppid) (process "ssh
address@hidden \"cd prj/dscm/services; ./x10-wish\"")])
...
then you can send and receive stuff, e.g.
(display "hey there" send-port)
and
(let ([response (read recv-port)])
... figure out what to do with it ...)
This chapter provides a starting overview of I/O in Scheme in general
