Explanation: | This message is associated with the Com-plete 3271 device module. It appears when the TEST REQUEST key was depressed by a 3271 terminal operator.
System action: | The input is ignored. Normal processing continues.

ZA40011 | LID=$1, TID=$2. TIDNOTF,IP=$3.
Explanation: | This message is associated with Com-plete's remote 3270 device support. It appears when input is received from a terminal that is not defined in the LGCB MACRO (TIBTAB) for the line from which the data was received. It also appears when input (other than sense and status) is received from a printer. The value $1 indicates the LID number of the line from which the input data was received. The value $2 is the TID number of terminal on the control unit from which the input data was received. It is not necessarily the terminal which sent the input data. To determine this, examine the data printed as '$3' (explained below); however, in some situations in a multi-drop environment, the TID can be useful in determining which transmission control unit sent the input data.
System action: | Com-plete reads all of the input, acknowledges receipt of the input, discards the input and continues normal processing.
System programmer info: | This problem is normally caused by an incorrectly defined LGCB or by hardware errors. The ZA40011 message is normally printed when invalid input is received in response to a POLL/READ channel program, in which case, the data printed as '$3' has the following meaning: Bytes 0 and 1 contain the hexadecimal length of the input data. If byte 3 contains an SOH (x'01'), then bytes 7 and 8 contain the control unit poll address and device poll address that were sent by the control unit (in response to the POLL channel program). If byte 3 does not contain an SOH, then bytes 4 and 5 contain the CU and device poll addresses instead of bytes 7 and 8.
Computer operator info: | This message is normally caused by hardware errors that are usually temporary. It is also normal for this message to be issued when remote terminals have recently been installed and have not yet been defined to Com-plete . If this message continues to appear, notify the Com-plete N system programmer.

ZA40012 | LID=$1, TID=$2. STATUS MESSAGE-S/S=$3.
Explanation: | This message is associated with the Com-plete 3271 device module. It appears when the sense and status message S/S=z for a 3271 control unit is received. For more information, refer to the appropriate hardware manual for an explanation of the status bytes.
System action: | Normal processing continues.

Explanation: | This message is associated with the Com-plete 3271 device module. It appears when three consecutive status messages indicating that intervention is required were received during a specific poll.
System action: | The terminal identified by LID xxx, TID yyy is dropped from the poll list. Normal processing continues.
Computer operator info: | Have TID yyy turned on.

ZA40014 | LID=$1, TID=$2. SPECIFIC POLL IS ABOUT TO BE ISSUED
Explanation: | This message is associated with the Com-plete 3271 device module. It appears when a specific poll is about to be issued for LID xxx, TID yyy.

ZA40016 | LID=$1, TID=$2. UEX WITHOUT EOT. ATTEMPTING TO CLEAR VIA READ.
Explanation: | This message is associated with the 3271 device module and indicates that a unit exception was received without reading an EOT.
System action: | The device module reads the line to clear it, then resumes the poll of the line.
Computer operator info: | If this method occurs occasionally, it should not cause concern. If it occurs frequently, it indicates a line problem and the line should be checked. This type of line error is usually caused by noise on the line, and the read of the line will eliminate it.

ZA40017 | LID=$1, TID=$2. ENABLE FAILED FOR LINE, LINE IGNORED.
Explanation: | This message is associated with the 3271 device module and indicates that the attempt to enable the line has failed.
System action: | The device module sets the line status to IGNORE. A subsequent restart of the line will retry the enable.
System programmer info: | This problem may be caused by the wrong CUU in the TIBTAB definition for the line.
Computer operator info: | If a restart of the line causes the same message, there is probably an error in the hardware or the software definition of the line.

ZA40018 | LID=$1, TID=$2, SLOW POLL INITIATED.
Explanation: | This message is associated with the 3271 device module and indicates that the device module received an excessive number of timeouts from the control unit for TID nnn.
