Device Errors
Two error messages can occur when attempting to direct an operation to an 110 device that
is not ready for use. A printer which is out of paper or no device at a specifed select code are
examples. The first message that appears is -
I / 0

If the condition is not corrected, the machine beeps intermittently and the following mes-
sage replaces the first -

The 110 device can be made usable by correcting the error (loading paper, or changing the
select code, for example), then executing the READY# command -
READY# select code
This command readies the 110 device and the operation which was attempted is attempted
again. The select code must be specified by an integer.
If you get an 110 error on select code 0 and the printer is not out of paper, call your Sales
and Service Office.
In some cases, such as an interface which is not connected. READY # for that select code
may not solve the I/O error. In this case, STOP should be pressed to regain control of the
computer. Be sure to turn the power off before inserting an interface. After the problem is
remedied, the operation or program can be tried again.
If you get an 110 error and you have an ON KBD statement in effect, you must press STOP
to gain control of the computer. Otherwise, the READY # command will be trapped by ON
KBD.
