Go back to the categories of Error Identifiers.

MPQP ADPERR

Error Description: MPQP ADAPTER ERROR

This error is logged by the MPQP device driver when invalid conditions are returned by the adapter code or the adapter is not functioning.

DETAIL DATA

File Name Module and line number where the error occurred.
Port Number Port number generating the condition.
Command Command generating the condition.
Receive Error Indicates the type of error that caused the receive error threshold to be exceeded. Refer to sys/mpqp.h for the codes that correspond to each error type.

MPQP ASWCHK

Error Description: MPQP ADAPTER SOFTWARE CHECKSUM ERROR.

This error is logged by the MPQP device driver when checksum on adapter software did not compare.

Refer to Detail Data under MPQP ADPERR.

MPQP BFR

Error Description: MPQP BUFFER ALLOCATION

This error is logged by the MPQP device driver when the system is unable to allocate a needed memory resource to the driver.

Refer to Detail Data under MPQP ADPERR.

MPQP CTSDRP

Error Description: MPQP CTS DROPPED DURING TRANSMIT

This error is logged by the MPQP device driver when CTS (clear to send) is dropped while a transmission is in progress.

Refer to Detail Data under MPQP ADPERR.

MPQP CTSTO

Error Description: COMMUNICATION PROTOCOL ERROR

This error is logged by the MPQP device driver when CTS (clear to send) fails to come on during transmission.

Refer to Detail Data under MPQP ADPERR.

MPQP DSRDRP

Error Description: MPQP DSR DROPPED

This error is logged by the MPQP device driver when DSR (data set ready) is dropped while DTR (data terminal ready) is still on.

Refer to Detail Data under MPQP ADPERR.

MPQP DSROFFTO

Error Description: MPQP DSR OFF TIMEOUT

This error is caused by starting a call while the DSR (data set ready) is on. If the DSR is on before the adapter drives DTR, the adapter assumes the previous call is still in progress. This is a security measure to ensure the previous session was terminated before the next call starts.

Refer to Detail Data under MPQP ADPERR.

MPQP DSRTO

Error Description: MPQP DSR TIMEOUT

This error is logged by the MPQP device driver when DSR (data set ready) fails to come on. It is a result of the modem failing to signal a ready condition.

Refer to Detail Data under MPQP ADPERR.

MPQP IPLTO

Error Description: MPQP INITIAL PROGRAM LOAD TIMEOUT

This error is logged by the MPQP device driver.

Refer to Detail Data under MPQP ADPERR.

MPQP QUE

Error Description: MPQP UNABLE TO ACCESS QUEUE

This error is logged by the MPQP device driver when it has been unable to access one of the command or response queues maintained by the adapter or driver code.

Refer to Detail Data under MPQP ADPERR.

MPQP RCVERR

Error Description: MPQP RECEIVE ERROR THRESHOLD EXCEEDED

If data is not received correctly, the driver logs an error. The application may recover by retransmitting. A certain amount of receive errors may be normal and is not cause for concern unless the errors become excessive and significantly degrade throughput.

Refer to Detail Data under MPQP ADPERR.

MPQP RCVOVR

Error Description: MPQP RECEIVE OVERRUN

This error is logged by the MPQP device driver when the driver is unable to provide adapter code with transfer buffers fast enough to keep up with incoming data, possibly resulting in data loss

Refer to Detail Data under MPQP ADPERR.

MPQP X21CECLR

Error Description: MPQP X21 CALL ESTABLISHMENT CLEAR

This error is logged by the MPQP device driver if the network has cleared a call, usually due to an error. If CPS data is returned, consult the CPS number to find out the reason for the clear.

Refer to Detail Data under MPQP ADPERR.

MPQP X21CPS

Error Description: MPQP X21 CALL PROGRESS SIGNAL

This error is logged by the MPQP device driver when an X.21 call progress signal is received.

Refer to Detail Data under MPQP ADPERR.

MPQP X21DTCLR

Error Description: MPQP X21 DATA TRANSFER CLEAR

This error is logged by the MPQP device driver when an unexpected X.21 clear is received during data transfer state.

Refer to Detail Data under MPQP ADPERR.

MPQP X21TO

Error Description: MPQP X21 TIMEOUT

This error is logged by the MPQP device driver if the X.21 subroutine does not complete because the timer expired. The timer is indicated in the detail data.

Refer to Detail Data under MPQP ADPERR.

MPQP XFTO

Error Description: MPQP TRANSMIT FAILSAFE TIMEOUT

This error is logged by the MPQP device driver if transmission does not complete, usually due to the following reasons: CTS not returned by modem, or clocks not detected by port.

Refer to Detail Data under MPQP ADPERR.

MPQP XMTUND

Error Description: MPQP TRANSMIT UNDERRUN

This error is logged by the MPQP device driver when the driver or adapter code is unable to provide communications hardware with data fast enough to maintain protocol timing. SYN characters will be inserted to maintain timing.

Refer to Detail Data under MPQP ADPERR.
