•SNA IMF/iX does not support the numeric lock feature.

•Pass Thru mode does not support slave printers (printers attached to terminals).

Functional Specifications

•SNA IMF/iX emulates the base function set of the IBM 3274 terminal controller; the base set does not include color, graphics, programmed symbols, or extended high- lights.

•SNA IMF/iX supports communications to an IBM System/370 (or compatible) mainframe running either the MVS/SP, MVS/XA, DOS/VSE, or VM operating systems with ACF/VTAM through an IBM 37xx communi- cations processor running ACF/NCP.

•SNA IMF/iX supports communications with an IBM S/36 running SSP or an IBM/38 run- ning CPF or an IBM AS/400 running OS/400.

•The SNA Link/iX product supports Physical Unit Type 2 or 2.1 protocols; SNA IMF/iX provides Logical Unit Type 1,2, and 3 emula- tion over the link. The SNA Link/iX or SNA/Token Ring Link/iX can support inter- active (SNA IMF/iX and SNA DHCF/iX), batch (SNA NRJE/iX), and programmatic (LU6.2 API/iX) communications simultane- ously over a single link to an IBM host.

•In Pass Thru mode, SNA IMF/iX emulates the IBM 3278-2, 3278-3 and 3278-4 display stations and IBM 3287 printers.

•SNA IMF/iX supports up to 127 devices (ter- minals, printers, or application programs) concurrently per SNA link with MPE/iX Release 4.0 or later.

•The HP 700/94 terminal is recommended for use with SNA IMF/iX in Pass Thru mode as it offers the greatest performance and func- tionality. SNA IMF/iX also supports null suppression mode on HP 700/94 terminals which result in further performance improvements.

•The following terminals support Modified Data Tags and, consequently, provide a 10-

50% performance improvement in Pass Thru mode and greater functionality over other terminals.

–HP 700/96

–HP Vectra

–PC with Reflection 7 PLUS Version 3.3 (or later)

•In Pass Thru mode, non-MDT terminals are not supported with all host applications that are sensitive to nulls and blanks. In these circumstances, an MDT terminal will func- tion properly and is strongly recommended to be the terminal of choice.

•The following terminals are supported with HP 3000 MPE/iX systems in Pass Thru mode via the DTC attachment.

–HP 700/92

–HP Vectra PC with Advance Link 2392

–HP Vectra PC Reflection 7 PLUS, Version 3.3 (or later)

•SNA IMF/iX supports the write optimized feature for improved performance in Pass Thru mode with the following terminals:

–HP 700/92

•With the HP X.25/iX Network Link (36939B) and NS 3000/iX Network Services (36920B), SNA IMF/iX supports these terminals when they are directly attached to an HP 2334A Plus or HP 2335 PAD.

This feature is supported on SNA IMF/iX or SNA IMF/V (30247A) only and is NOT supported on the IMF/V (30250A) product. Other Pass Thru-supported terminals configured to be one of the terminals listed above are NOT supported.

•The HP 700/94, HP 2394A, HP 150, HP 700/92, and HP 2392A terminals support a 19.2 KB/s connection to the HP 3000.

•The following terminals support multiple levels of “rolling softkeys” allowing up to 96 user-definable function keys.

– HP 700/94

– HP 2394A

•SNA IMF/iX supports any HP system printer.
