DEC-VT220-Terminal

The Digital VT220 is a high-productivity video display terminal that combines advanced capabilities with human engineering for ease of use.

Key Features:

• Display: Monochromatic text display with 24 lines and 80 or 132 columns, featuring a 10x10 dot matrix for crisp text. It supports various display attributes like blinking, bold, underline, normal/reverse video, and double-height/width characters. A CRT Saver feature extends screen life by blanking after inactivity. Composite video output is available for auxiliary monitors.
• Ergonomics & Usability: Designed for user comfort, it features an optimized keyboard height, logically grouped keypads, and 25 function keys (15 programmable) to reduce fatigue and errors. The 105-key keyboard is detachable and lightweight. The compact, wedge-shaped monitor has a nonglare screen available in white, green, or amber, with adjustable tilt, contrast, and brightness controls. Plain-language setup menus (English, French, German) allow easy configuration.
• Connectivity & Compatibility: It operates in VT200, VT100, and VT52 modes, supporting standard ANSI functions (except VT52). It connects to host computers via full-duplex asynchronous communication (EIA RS-232C, RS-423, 20mA) at speeds up to 19,200 baud. It includes a serial printer port for local printing without host intervention. An optional integral modem (300/1200 baud, auto-answer) is also available.
• International Support: The VT220 is designed for global use with multinational character set support, multiple language keyboards, and a universal power supply.
• Advanced Capabilities: Features like "selective erase" allow efficient form-filling by clearing specific data while retaining the form layout. It includes a 254-character input buffer and XON/XOFF support to prevent data loss.
• Reliability: Built with minimal mechanical switches, the terminal is highly reliable, requires no preventive maintenance, and features self-test diagnostics for easy troubleshooting.

Overall, the VT220 is a versatile, user-friendly, and highly productive tool suitable for a wide range of environments.
