Hi Scott,

Do any of these links help?

http://cis.kutztown.edu/~frye/cgi-bin/unixManPages.cgi?st+7D
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=115&prodSeriesId=63988&prodTypeId=12169&objectID=lpg51061
http://www.sunmanagers.org/archives/1995/0984.html

There were also a couple hits to the drivers if those would help.

Thanks,

William
