In-band flow control was always a pain in the rear.  Of course, it was also a cheap solution to a problem.  Better async multiplexers and terminal servers, however, had full modem control, and the VMS terminal driver supports out-of-band flow control at least in VMS V5.x.  I would like to know whether hardware flow control was added in V5.x or earlier.  This is out of historic curiosity.
