The following terminal types files are supported on the ATP and ADCC terminal/printer controllers with MPE V T-MIT or later (MPE V version G.01.00 or later):

  • 6, 9, 10, 12, 13, 15, 16, 18, 19, 20, 21, 22, TTPCL18, TTPCL19, TTPCL22, and TTPCL26.

DTS on MPE/iX computers supports three terminal types and four printer types:

  • Terminal type 10.

  • Terminal type 18.

  • Terminal type 24.

  • Printer type 18.

  • Printer type 21.

  • Printer type 22.

  • Printer type 26.

Table A-1 “MPE/iX Terminal Types Overview” and Table A-2 “MPE/iX Printer Types Overview” provide an introduction to the MPE/iX terminal types and printer types by comparing them to the MPE V terminal types that are the most similar. See Table A-1 “MPE/iX Terminal Types Overview” for the terminal types that apply to terminals, and Table A-2 “MPE/iX Printer Types Overview” for the MPE V terminal types and MPE/iX printer types that apply to printers.

Table A-1 MPE/iX Terminal Types Overview

MPE/iX Terminal TypeSimilar MPE V Terminal TypeDifferences
1010Enhanced XON/XOFF protocol on MPE/iX. No ENQ/ACK protocol on MPE/iX.
1818Enhanced XON/XOFF protocol on MPE/iX.
2424For terminal devices connected via PAD.

MPE/iX Printer TypeSimilar MPE V Terminal TypeDifferences
1818Enhanced XON/xoff protocol on MPE/iX
21, 22, 2621, 22, 26Enhanced XON/XOFF protocol on MPE/iX. No ENQ/ACK protocol on MPE/iX. Printer initialization string of MPE V's TTPCL22 is used.Printer status checks are done less frequently on MPE/iX; status requests are not sent after each printed line.

 

As devices are moved from an MPE V system to an MPE/iX system, see Table A-3 “Terminal Type Migration for Terminals” and Table A-4 “Terminal Type Migration for Printers” to decide which terminal or printer type to use with each of your asynchronous devices.

MPE V Terminal TypeDescriptionUse MPE/iX Terminal TypeComments
6, 9Non-HP hardcopy device needing delays after linefeed or formfeed.NoneDevices that need delays are not supported on MPE/iX.
10General HP CRT terminal using both ENQ/ACK and XON/XOFF protocol.10Only XON/XOFF protocol is used on MPE/iX.
128-bit character version of terminal type 10. Used with languages that need extended character sets.10Bits per character no longer defined by terminal type.
13Terminal type 10 with no echo or ENQ/ACK protocol. Used for plotters or the HP 2601 printer.NoneSimilar terminal type can be created with TTUTIL.
15, 168-bit and 7-bit HP 2635 hardcopy terminal.NoneThese terminal types specify use of a backspace response action not supported on MPE/iX.
18Terminal type 10 without ENQ/ACK protocol or a read trigger. Used with non-HP devices.18Enhanced XON/XOFF protocol is used on MPE/iX.
24Terminal type used for PAD terminals supporting page block mode.24Terminal type used for PAD terminals supporting page block mode. (Note that the block mode support is for VPLUS block mode only.)

18Non-HP devices or application printers18MPE V's terminal type 18 and MPE/iX's printer type 18 are exactly the same except that an enhanced XON/XOFF protocol is used on MPE/iX.
TTPCL18Terminal type 18 with a printer initialization string and an XOFF timer. Used with HP 2687A.18The HP 2687 A is not supported on MPE/iX.
19Remote serial spooled printer.21Status checking is done less frequently on MPE/iX. The printer initialization string is the same as MPE V's TTPCL22.
TTPCL19PCL remote serial spooled printer.21Status checking is done less frequently on MPE/iX.
208-bit serial spooled printer.22Status checking is done less frequently on MPE/iX. Initialization string is the same as MPE V's TTPCL22.
