Regarding the use of RI on Able DH/DMs for flow control.  We have
been doing this for over a year now with our LocalNet units.  This
allows us to have totally out-of-band flow control, which is great if
the unit on one end is talking 4800 baud to a modem, while the unit on
the other end is talking 9600 baud to the computer (as mine is at this
very moment).  The only problems we encountered were with our DEC-20,
which thinks it knows how long it should take for a string to be
transmitted.  If it is flow controlled for too long by this method
(which is totally invisible to the host), it gets upset.
