Section 3: Setting Up - SNA38 AXIS 570/670 MIO User’s ManualSNANote: o The AXIS 570/670 MIO can only be configured for use with asingle host, an IBM mainframe or an AS/400.o Although it is possible to define several logical units on the hostsystem the AXIS 570/670 MIO will only print one SNA job at atime. SNA jobs are held in a print queue within the AXIS570/670 MIO and are processed on a first-come-first-serve basis.Control Unit EmulationGeneral The AXIS 570/670 MIO may be set up to emulate either a LANattached IBM 3174 or IBM 5494 Control Unit. In themainframe/VTAM environment it must be set up to emulate anIBM 3174 (3270 CU mode). Proceed to Host Set-up - IBM Mainframe,on page 39 for information on the mainframe host setup.In the IBM AS/400 environment, the AXIS 570/670 MIO may be setup in either mode. We strongly recommend you choose IBM 5494emulation (5250 CU mode) to achieve maximum functionality. The5250 CU mode offers a significantly richer set of features forformatting text. Proceed to Host Set-up - IBM AS/400, 5250 CU mode,on page 45 for information on to set up the AS/400 for communicationwith an AXIS 570/670 MIO running in 5250 CU mode.If you have decided to run the AXIS 570/670 MIO in 3270 CU modein an IBM AS/400 environment you should proceed to Host Set-up -IBM AS/400, 3270 CU mode, on page 54.
