4B26I P UNIT EXCEPTION SYSnnn=cuu TI=xxxx DC=dddddddddd DECB-=aaaaaa
Cause: Unit exception.
For the local 3270 device, a device affected by a command is busy. It may occur when an
operator by action of certain keyboard functions or the identification card reader has made the
device temporarily busy. Time is needed for the device to become not busy. No system or
operator action is required.
For devices other than the local 3270 device, this is probably a hardware error.
System Action: Processing continues.
Programmer Action: none.
Operator Action: The condition that caused this status is device and command dependent. If
this message is issued frequently, a hardware problem may exist.
If the problem persists, have the EREP output (see DOS/VS SADP) available for problem
