We have used a 3rd party product from Dilog (model CQ-1620) on our
MVIIs and were quite satisfied with them.  They emulate a DHV11 quite
faithfully (including the fact that they recognize only one level of
interrupts, just as the DHV11 does :-( ).  In VMS 4.7 DEC did not
allow you to enter a speed greater than 19200, so Dilog used an
improbable speed=(4800,134) as the sign that you really wanted
a speed of 38400.  There were other 3rd party products available when
we were shopping and we looked at one other vendor, but their product
did not perform correctly in our system.
