2.2 The IBM 7171 ASCII Device Attachment Control Unit - Index of

717110 LOGON Errors: Failure at STAGE 2 is the most frequent. Failure at thisstage is a result of:1. Incorrect cabling. Transmission requires CTS and DSR are presented. Be surethe cable conforms to IBM 7171 ASCII Device Attachment Control UnitDescription and Planning Guide. It is the user's responsibility to see that thecable conforms to the specifications presented, usually ABEND -3,-5,and -6.2. TYPETERM is not a valid terminal type, usually ABEND -3.3. The ZAP interface password must be correct and unique with respect to theMaintenance Facility password, usually ABEND -3.4. If modems are in use, then time must be given to allow the modems to establishthe communication protocol. This time varies from fractions of a second up to30 seconds. This modem communication setup delay time is modem dependentand it is the user's responsibility to control the environment, usually ABEND-5,and -6.5. Port 0 was past the ENTER TERMINAL TYPE STATE. usually an Echobackerror stating a X' OD' was sent and X' 1B' was received. The X' 1B:' is anescape character associated with a cursor reposition function of the active terminaltype. ABEND -5.6. A DOS extension running in background or on an interrupt driven basis whichuses too many of the CPU cycles which the 717110 utility needs for servingthe RS-232 port, usually ABEND -6.Errors such as 2 and 3 can quickly be identified with the use of a terminal or aterminal emulation.For 2 get to the ENTER TERMINAL TYPE message. Press the Carriagereturn to see the VALID TYPES ARE list. Is TYPETERM is in the list? Ifnot the user will need to log onto the Maintenance Facility to check the terminalnames list which begins at DCOO:300. If assistance is needed refer to4.6.1, "Terminal Names List" on page 4-45.For 3ENTER M DCOO:2AO 8RESPONSE DCOO:2AO 16 hex digits your passwordIf this doesn't correspond with your password, either make note of the correctpassword or change it using the PW Z command.For 6 the user needs to know the programs which are currently running in thePC.For 1 and 4 it requires a closer look at the equipment. The cable is the mostfrequent cause of problems at the LOGON stage.717110 LOGON Sequence: This is a description of the events which must takeplace to successfully LOGON to the ZAP interface.C-60 IBM 7171 Reference Manual and Programming Guide
