Guys. Slow down. It is not a cable error. It is not a terminal error. If the system also
had the card already installed before it is also not an installation error. It is also
probably not an interrupt error.
I can go into more details behind the reasoning for this if people are interested.
Holm did mention that the card had been configured as a dhv11. That would suggest that the
card has been out, which is why I also wondered about installation. Point is, the
backplane here is one with only q-cd slots. Some cards have jumpers that should be set
different for q-q or q-cd slots.
The dhv11 uses dma for output. No interrupt until all data has been transmitted. Vms shows
device errors, and not a single char comes out. The error log can contain much more
detail. Someone already provided the command to see the error log. Post what that shows.
It might be informative. Broken clock is definitely a possibility.

(SYS$ERRORLOG:ERRLOG.SYS?)
Timeout: Is it perhaps expecting an interrupt but doesn't get one in reasonable amount of time? Maybe something
wrong in the interrupt
grant chain? Do you have an empty slot above this board into which
you
need to insert a grant continuity card?

Hey Guys...please read what I'already wrote to this problem.
Therie is no hole between the CPU and the MUX.
And yes, it feels like DMA or Interrupt Timeout, that's why I think
that
the clock crystal may be broken..
