This isn't too hard if you use stdin/stdout. But it does depend on
what you mean by send commands from the command line. If the process
is a daemon for example and it isn't stopped waiting for input then
its going to be hard! If its waiting on a socket then its a standard
ipc issue.

Assuming you mean something that normally interacts with a human
user then you can use things like expect to simulate user input.
Is that what you mean?
