+.Sh BUGS
+Several firmware revisions of the
+.Nm cgsix ,
+in particular those found in the SparcStation 5, have a
+bug that occurs when the screen control sequences for inserting blank lines
+(i.e., the control sequences produced by the
+.So al Sc and So AL Sc
+capabilities found in the
+.Xr termcap 5
+database) are used near the bottom end of the screen.
+This bug is most likely to be encountered during the
+use of a full-screen editor such as
+.Xr vi 1
+on the workstation's console.
+.Pp
+To work around this bug, the
+.Ev TERM
+environment variable should be set to
+.Sq sun-ss5 ,
+which is the same as the
+.Sq sun
+entry except without the
+.Sq al
+and
+.Sq AL
+capabilities.
