What is the test for appointing counsel to represent appellant on appeal?

We appointed counsel to represent appellant on appeal, and after examination of the record appointed counsel filed an opening brief raising no issues and asking this court to independently review the record. (People v. Wende (1979) 25 Cal.3d 436, 441-442.) On November 3, 2014, we sent letters to appellant and appointed counsel, directing counsel to immediately forward the appellate record to appellant and advising him that within 30 days he could personally submit any contentions or issues that he wished us to consider. Appellant did not respond.
