AMShellWrapper sending data to a running task - objective-c

Question

I'm in the process of converting AMShellWrapper to my own application that runs an SH file that has userinput. Therefore, I need to send data to a running task.
Any ideas?

You need a somewhat different approach along the lines of PseudoTTY.app!
