Predefined Mnemonic Spaces for Terminals

InterSystems IRIS provides two predefined mnemonic spaces for use with terminals:

^%X364 for ANSI X3.64 terminals
^%XDTM for DTM PC Console

If you make one of these mnemonic spaces active, you can use the control mnemonics associated with them in WRITE /mnemonic commands. You can also create your own mnemonic spaces. See Controlling Devices with Mnemonic Spaces for more information on mnemonic spaces.

The following sections describe the control mnemonics for these mnemonic spaces.

Mnemonic Space for X3.64

InterSystems IRIS provides a built-in mnemonic space for the ANSI X3.64 definition. This mnemonic space is the InterSystems IRIS routine %X364 in the manager’s namespace. To use routine %X364, either:

Have your InterSystems IRIS system manager enter %X364 as the default mnemonic space in the IO Settings configuration setting. From the Management Portal, select System Administration, Configuration, Device Settings, IO Settings.
Issue an OPEN command specifying this mnemonic space:
```
 OPEN "terminal"::"^%X364"
```

The following table lists the mnemonics.

Mnemonic Space for DTM PC Console

InterSystems IRIS provides the InterSystems IRIS routine %XDTM to match the mnemonics used in developing applications for DTM. This mnemonic space is available but is not set up as the default mnemonic space for terminals. If you port applications created for DTM to InterSystems IRIS, you can either:

Configure ^%XDTM as the default mnemonic space for terminals (MnemonicTerminal) in the Management Portal, or
Reference the ^%XDTM mnemonic space in the OPEN or USE command.

DTM Examples

UNIX®

  OPEN "/dev/tty04/"::"^%XDTM"

Windows

  OPEN "c:\sys\user"::"^%XDTM"

Then InterSystems IRIS can correctly interpret the DTM control mnemonics in WRITE /mnemonic commands, shown in the following table.
