VT100 Mode 18-1
18 VT100 MODE
The TEK933 utilizes a feature known as VT100 Mode. This mode enables your single
board computer to run without a local keyboard or screen. That is, operation can be
controlled via a remote terminal supporting VT100 Mode or a computer with a terminal
emulation program (for example, Telix, Procomm).
18.01 VT100 REQUIREMENTS
To use VT100 Mode, the board must be supplied with ±12 volts. This is the voltage
required by the RS232 drivers.
The terminal you are using should emulate a VT100 or ANSI terminal. Although this is
not an absolute requirement, strange characters may appear on screen if it does not.
This occurs because the VT100 recognizes these control characters, and causes them to
perform a specific function, for example, screen erase, cursor position, and so on.
