Preface
This publication is the NCR 56xx/Personas Self-Service Financial
Terminal Diagnostic Status Code Notebook. It documents the
M_STATUS and M_DATA returned in error log reports or
diagnostic reports although the diagnostics tests themselves are
described in the 56xx/Personas Services Aids Mini Manual
(SAMM), (publication ID: FM-0547).
By having the same page size as the SAMM, users of the SAMM
can include relevant pages from this manual in their SAMM
binders. The chapter names of this manual have been chosen to
match those of the diagnostics chapters in the SAMM to facilitate
this action.

37 Logical Connection reset. 39 DCE busy (RNR received). 46 Network diagnostic information. 47 DTE busy (RNR transmitted).
50 Modem failure. DSR has failed to switch ON after DTR was switched ON during OPEN.
51 Modem failure. CTS has failed to switch ON after RTS was switched ON.
52 Modem failure. CTS dropped while RTS was still ON or DSR dropped while DTR was still ON.
60 No DSA available to generate structures for a logical connection. 61 No DSA available to assemble/segment a message.
62 No logical channel available.
63 Logical Connection not closed/released. 69 A fatal communications error has been detected. 81 No Data Set Ready detected.
M_DATA
M_DATA contains further information on error reports. The
following information has been defined for the relevant
M_STATUS.
M_STATUS = 50 - 52
State of modem interface signals when modem failure is reported.
The M_DATA buffer contains one byte with the following layout:
M_STATUS = 10, 11, 17, 20 - 22, 29, 30, 39, 47
Level-2 report giving last ten or seven LPH states and the
command field of the frame causing the report. In cases where
frame reject data is present, the last seven states followed by the
FRMR data are reported, otherwise the last ten states are reported.
82 No Carrier (RLSD) detected. 83 No Clear To Send detected.
84 Timeout on transmit (no characters transmitted). 85 Timeout on receive (no characters received). 86 (Reserved).
87 Receiver overrun error.
88 Data mismatch. The data received was not the same as the test pat-tern transmitted.
89 No external turnaround detected. The Test Indicator failed to turn ON. 90 Data-mismatch or FCS error detected.
