The MS-DOS Prompt Edit file window opens.

1. Press Ctrl+P and then release the keys.

2. Press and release the Esc key. The editor inserts an arrow symbol pointing to the left,

which indicates to the printer that the text following the symbol is a command, not text
that should be printed.

A left-arrow symbol should appear, which indicates to the printer that the text following the
symbol is a command. If the left-arrow symbol does not appear, or if another symbol
appears, then delete any characters or spaces and repeat steps 1 and 2 until the left-arrow
symbol appears.

3. Type, in uppercase letters, the remainder of the command after the symbol.

Following is an example of the MS-DOS Editor window, when restoring the serial number.
