The only method I'm aware of for pushing characters to a terminal
requires using ioctl, and I think (but am not certain) this only works
if the process in question is the session leader. In C, this looks like
"ioctl(tty, TIOCSTI, data)" where "tty" is a file descriptor for the
terminal. Maybe you could create a wrapper program that uses ioctl to
push bytes into the input buffer then spawns a shell.
