I assume the current interface reads a line at a time from the console.
You can do this asynchronously by sending packets directly to the console
handler (you can get the console handler's address from somewhere in your own
Process structure, I think). Then you can wait on both the reply port for
your packet and the AREXX port at the same time.

If the application already uses the AmigaDOS Read() calls, then this should
not take too much effort. If it uses unix-like fread() type calls, then
you might have some more work to do.
