Features & Specifications » DEC VT320 Terminal
|
|
|
|
The VT320 can work with standard American National Standards Institute (ANSI) functions.
|
|
Set-Up
|
|
• The VT320 has a series of set-up screens that list the operating features of the terminal. You can display these screens and change feature settings from the keyboard.
|
|
• For example, the VT320 has an On-Line/Local feature. You can only set this feature from set-up. When you use the "On-Line" setting, the VT320 can communicate with your host system.
|
|
• To enter set-up, you press the Set-Up key. Chapter 4 describes set-up.
|
|
Emulations
|
|
•
The VT320 can also operate as a VT200 series, VT100 series, or VT52 terminal. You select the operating mode from the General Set-Up screen. There are four possible settings.
|
|
• VT300 mode, 7-bit controls
|
|
• VT300 mode, 8-bit controls
|
|
• VT100 mode
|
|
• VT52 mode
|
|
• The factory default setting is VT300 mode, 7-bit controls. This mode is fully compatible with VT200 series terminals. Use this mode for VT200 applications. Factory-default settings are the initial settings the terminal uses when shipped from the factory. These settings are permanently stored in the terminal's memory. You can use set-up to reset the VT320 to the factory-default settings at any time.

|
Character Sets
|
|
•
The VT320 has two types of built-in character sets, for use with different types of computer systems.
|
|
• 8-bit multinational sets
|
|
• 7-bit national replacement character sets
|
|
• from 2 multinational sets or 12 national replacement character sets (NRCs). You use the Character Set Mode feature in the General Set-Up screen to select the type of character set: "8-Bit Characters" for multinational sets, or "7-Bit Characters" for NRC sets.
|
|
Multinational Character Sets
|
|
• When you first use your VT320, the terminal uses the DEC Multinational character set. This set contains the characters for the English language, plus most characters used in the Western European languages. Use this set with applications that require strict compatibility with VT200 series terminals.
|
|
• You can also select the ISO Latin-1 character set of the International Standards Organization. ISO Latin-1 is the new industry-standard set. It is similar to the DEC Multinational character set, with a few different symbols and characters.
|
|
• the standard ASCII character set of the American Standard Code for Information Interchange.
|
|
National Replacement Character Sets
|
|
•
NRC sets are for 7-bit computing environments. Each NRC set is for a particular Western European language or dialect. NRC sets are similar to the ASCII set, but replace a few ASCII characters with characters used in that language or dialect.
|
|
• You can only use one NRC set at a time. You select the NRC set by setting the Keyboard feature in the Set-Up Directory.
