Two unrelated questions

[The Mad Mathematician]

I have two unrelated problems on two separate systems.

First, and more immediate, I am trying to add a Micropolis 1355
ESDI style to a MD21 with another of the same type already installed
and running.  I need to know what settings on the drives and board to
set to run on a Sun 3/60.  The board is currently set at SCSI ID 0.
On the back of the drives I see 8 jumper pairs, and what appears to
be a terminator resistor.  On the board I see a 8 dip switch panel.
ANY information would be helpful, as I am doing this without any
documentation.

Second, I have a Sun 386i running SunOS 4.0.3, and a program called
EPLUS.  We have an Okidata 400 (?) laser printer attached as lp1
to /dev/ttya.  We occasionally manage to freeze the print queue,
getting a message: 'Waiting for lock on /dev/ttya'
Nothing I do short of emptying the queue clears this up.
Any ideas on how to free the queue, or, preferably, prevent this
from happening will be appreciated.

Thank you.
