I am re sending this summary because I forgot to mention the help provided by
Ric Anderson <> His insight to try all the device names was
invaluable. My thanks to: "David A. Harvey" <> who
provided the insight to the actual configuration and my problem
(compression). Also thanks to Jacques Rall <> who
reinforced Dave's suggestion to check the dip switches on the drive.

>Changing the DIP switches did the trick. After setting the compression
switch to off - this required opening the external drive case-, I was able
to access the drive as /dev/rmt/2l. Thus solving my problem - making use of
the free hardware.
>Thanks to all who responded. I have included the initial post below:
