March 3, 1980 Configurations (Terminals)
The following 3270 devices (although supported by VM/370) are not
supported by the 3270 Data Analysis-APL feature and therefore cannot be
used to display, print, or enter APL characters: • The 3284 Printer, Model 3 • The 3275 Displa y Station, Model 2 • The 3288 Printer, Model 2 • The 3286 Printer, Model 3 • The 3274 Control Unit, Models 1B and 1C • The 3276 Control Unit Display Station, Models 2, 3, and • The 3278 Display Station, Models 2, 2A, 3, and 4 • The 3289 Line Printer, Models 1 and 2
Note: With the 3270 Data Analysis-APL feature installed, 3270 functions remain operational. The only exception is key, which is not supported by VM/370. 4

the backtab VM/370's support of the 3270 text feature allows the user to key in, as
well as display and print, all the special characters.
The 3270 Data Analysis-APL feature (#1066) is required on the
following 3270 devices if they are to be used with special text
characters: • 3271 Control Unit, Model 2 • 3272 Control Unit, Model 2 • 3284 Printer, Model 2 • 3286 Printer, Model 2 • 3287 Printer, Models 1 and 2
The 3277 Display Station Model 2 must be equipped with the text keyboard
(#4639). For a more detailed description of VM/370's text support, see

The IBM 3767 Communication Terminal, ,Models 1 and 2, is supported when
it operates as an IBM 2741 Communication Terminal and is attached to a 3704 or 3705 Communications Controller. It requires the following
features on either switched or nonswitched point-to-point lines: • 2741 START/STOP (17113) • EBCDIC (19391) or Correspondence (19381) keyboard • Duplexed, switched or nonswitched line (#9404) for connecting to a Western Electric 103A2 (or equivalent data set) • One of the following:
--EIA Interface with Clock (#3719) at 300 bps --1200 (15505 or The following features, although not
convenience and usability of the terminal:
required, enhance the • Alternate Character Set (#1291), plus a defined character subset for
the keyboard:
--If the primary character set is Correspondence (19381), the
alternate character set can b.e APL (#9383) or EBCDIC (19382). --If the primary character set is EBCDIC (19391), the alternate
character set can be APL (#9393) or Correspondence (19392). Line control is PTTC/EBCD with this feature. • Acoustic Coupler (#1110) at 300 bps
Transmission Control Units VM/370 supports the following transmission control units: • IBK 2701 Data Adapter Unit • IBK 2702 Transmission Control • IBK 2703 Transmission Centrol • IBM Integrated Communications Attachment (ICA), (#4640) • IBM 3704, 3705-1, and 3705-11 Communications Controllers 2701 REQUIRED FEATURES I. For line control of CPT-TWX (Kodel 33/35) terminals and the 3101 I display terminals, the Telegraph Adapter Type II (#7885) is required. • For 2770, 2780, 3270, 3770 (as a 2770; 3776 also as a 3780), and 3780 the following are required: --Synchronous Data Adapter Type II (#7698)
--EBCDIC code (#9060) --EBCDIC transparency (#8029) 120 IBK VK/370 Planning and System Generation Guide
