Scanner Mode Control Commands Details
Connected The scanner runs under the control of the control program. The
errors on the CCU I/O instructions are reported to the control
program, and the errors on the MOSS I/O instructions are reported
to the MOSS.
Disconnected The scanner does not run under the control of the control
program but under the control of the MOSS microcode. Only the
MOSS 1/0 instructions are executed. Any instruction from the CCU
is rejected (IOC time out), or not answered.
