i believe pcmd may be the kind of utility you are looking for.  this is the header info citing attribution:

* pcmd: Push characters into tty input buffer.
*
* 1988-09 John H. DuBois III (john@armory.com)
* 1989-03-13 Last BSD version
* 2002-03-18 UnixWare port. Use getopt.
* 2004-05-10 Linux & MacOS X port. Use termios.

i routinely use this on linux, bsd, macos.  if you have trouble finding a source repository for it, pm me.
