Erasing
Erasing deletes characters in the wireless station’s display
without affecting other characters. Erased characters are
lost. Cursor positioning does not change when characters
or lines are erased. Table 8-23 lists erasing sequences and
the action taken by the wireless station.

next Pn-1 character. A parameter of 0 or 1 erases
