to remind an operator to change the paper or to make another
adjustment to the printer. Note to Apple users: Entering a
CHR$(7) will sound AppZe’s bell; the code will not be sent to
SR-10/15.
You can try this by typing:
LPRINT CHR$(7);
There are two other codes that affect the bell. One disables the
bell, so that SR-lo/15 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.

Note: If your computer does not support lowercase characters, use
CHR$(121) for “y”.
n Initializing SR- lo/ 15
Up to now when we wanted to reset SR-lo/15 to the power
on condition we have had to either turn the printer off and then
on again, or to send the specific codes that reset the particular
features. There is an easier way. The control code < ESC > “a”
will reset all of SR-10/15’s features to the power on condition
(as determined by the DIP switches), with two exceptions. Those
exceptions are that < ESC > “@” will not erase any characters
that you have stored in SR-10/15’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 SR- 10/l 5’s RAM (this chapter
will tell you how to create a macro).
n Putting SR-lo/15 to sleep
You know how to put SR-lo/15 off-line with the On Line
button.
SR- 10/l 5 has another off--line state that can be controlled
from your computer. When you turn SR- 10/l 5 off--line from your
computer, SR-lo/15 will ignore anything that you send it, except
