|

|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
2020-07-22 20:01:21 +02:00
|
|
|
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.
