[net.emacs] Buffer Shells in CCA EMACS

z (03/22/83)

CCA EMACS has been modified to communicate with shells and other
subprocesses running in buffers via pseudo-terminals (pty's) instead of
pipes on those systems which support pseudo-terminals.  On other
systems, and on those systems where there are no free pseudo-terminals
available, EMACS will continue to use pipes.  The advantages of using
pseudo-terminals is twofold:  first, all programs think that the are
talking to a real tty, and behave as they do outside of EMACS; and
second, full job control is available when running the C shell in a
buffer.
