Maybe this can help on some platforms?

process-running-child-p is a built-in function in `C source code'.
(process-running-child-p &optional PROCESS)

Return t if PROCESS has given the terminal to a child.
If the operating system does not make it possible to find out,
return t unconditionally.

Anyway, one could just send the partial line plus TAB to the other
application, anyway.  If it just echoes it, no harm is done.  The
behavior should work for most applications that use either a normal
stty setting or readline.
