SneciaI Features of the Radix Printer

condition we have had to either turn the printer off and then on
again, or to send the specific codes that reset the particular fea-
tures. There is an easier way. The control code (ESC) "a" will
reset all of Radix's features to the power on condition (as deter-
mined by the DIP switches), with two exceptions. Those excep
tions are that (ESC) "@" will not erase any characters that you
have stored in Radix's RAM memory (Chapter 11 tells you how to
create your own characters), and it won't erase the macro if you
have one stored in Radix's RAM (this chapter will tell you how to
create a macro].
Putting Radix to sleep
You know how to put Radix o#line with the On Line button.
Radix has another off-line state that can be controlled from your
computer. When you turn Radix off-line from your computer,
Radix will ignore anything that you send it, except for the code to
go on-line again. CHR$(lS) is the code to turn Radix off-line;
CHR$(17) returns Radix to on-line status.
Printing to the bottom of the sheet
Sometimes when you are using sprocket paper you may want
to print near the bottom of the last sheet. The paper-out detector
usually stops Radix when you are about 3 inches from the bottom
of the sheet. This is to notify you if you are running out of continu-
ous paper.
Radix has the ability to print right to the bottom of the sheet.
You can disable the paper-out detector so that it doesn't stop the
printer. This will allow you to print to the end of the sheet, and
even beyond if you are not careful. The codes to control the paper-
out detector, along with the other codes that we have just learned
are in the following table.
