- 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.
