\chapter{Escape-Sequences}

The following Escape-Sequences are supported by the VT132 Terminal.

The VT132 in VT100 mode supports sequences from the real DEC VT100, but also some sequences from later models like
VT102, VT220, VT510 or VT520.

Also, sequences from VT52 are available in VT52 mode of the VT100 personality (and using the VT52 personality); these are shown at the end.

Furthermore, some sequences that are used by ANSI.SYS (from DOS) are available.

Sequences from other personalities are not shown in this Guide.
