The DZ11 can run at 19.2KB as one of its standard speeds. Most UNIX DZ11 drivers implement this as the "EXTA" DH11 equivalent. I once used 19.2KB on a PDP-11/34 and saw no noticeable speed improvement since the kernel could not keep up with the device capacity at that speed. (The DZ11 interrupts on every character in or out. That is why the KMC11B controller is so important if you have DZ11s.)
