I don't understand where you are comming from.  I wasn't sniping him, I
tried to answer his question, AND complain about the general state of
affairs.

Since I didn't want to go in to the requirements for implementing all of
these things, I tried to make a simple statement.  I didn't want to
consider things like homemade PTY or SXT drivers and such.  USUALLY a
system that has the "facilities" [system calls / drivers] for
implementation of such features will also have some user-level commands
for exploiting these facilities, ie. shl will be there if you have
sxt's, and systems with pty's [nice for emacs] will ususally have
job-control facilities built into the shell as well.  BTW: Emacs may
still not work with interactive processes on systems that have no PTY's
or Streams, or multiplexed I/O.

Again, remember I was making a general statement, and I wanted it to
apply to the generally available systems that the perpetrator of the
question, and readers of the reply, are likely to run across.
