* to remind an operator to change the paper or to make another
adjustment to the printer. Note to Apple users: Entering a
CHR$(7) will sound Apple’s bell; the code will not be sent to
SD-10/15.
You can try this by typing:
LPRINT CHR$(7);
There are two other codes that affect the bell. One disables the
bell, so that SD-lo/l5 will ignore a CHR$(7), and the other turns
the bell back on. All three codes that affect the bell are shown
in the following table.

Up to now when we wanted to reset SD-lo/l5 to the power
on condition we have had to either turn the printer off and then

features. There is an easier way. The control code < ESC > “@”
-
will reset all of SD-lo/l 5’s features to the power on condition -
(as determined by the DIP switches), with two excep.tions. Those
exceptions are that < ESC > “@” will not erase any characters
that you have stored in SD-lo/l 5’s RAM memory (Chapter 9
tells you how to create your own characters), and it won’t erase
the macro if you have one stored in SD-lo/l 5’s RAM (this chapter
will tell you how to create a macro).
W Putting SD- IO/l 5 to sleep
You know how to put SD-lo/l5 offlline with the On Line
button. SD-lo/l 5 has another ofFline state that can be controlled
from your computer. When you turn SD-lo/l 5 off-fine from your
computer. SD- 1 O/l 5 will ignore anything that you send it, except
