public class vt320

extends Terminal

implements TerminalHost

<PARAM NAME="VTcolumns" VALUE="80">

Sets the columns of the terminal initially. If the parameter VTresize is set to screen this may change, else it is fixed.

<PARAM NAME="VTrows" VALUE="24">

Sets the rows of the terminal initially. If the parameter value of VTresize screen this may change!

<PARAM NAME="VTfont" VALUE="Courier">

Sets the font to be used for the terminal. It is recommended to use Courier or at least a fixed width font.

<PARAM NAME="VTfontsize" VALUE="14">

Sets the font size for the terminal. If the parameter value of VTresize is set to font this may change!

<PARAM NAME="VTresize" VALUE="font">

This parameter determines what the terminal should do if the window is resized. The default setting font will result in resizing the font until is matches the window best. Other possible values are none or screen. none will let nothing happen and screen will let the display try to change the amount of rows and columns to match the window best.

<PARAM NAME="VTscrollbar" VALUE="false">

Setting this parameter to true will add a scrollbar west to the terminal. Other possible values include left to put the scrollbar on the left side of the terminal and right to put it explicitely to the right side.

<PARAM NAME="VTid" VALUE="vt320">

This parameter will override the terminal id vt320. It may be used to determine special terminal abilities of VT Terminals.

<PARAM NAME="VTbuffer" VALUE="xx">

Initially this parameter is the same as the VTrows parameter. It cannot be less than the amount of rows on the display. It determines the available scrollback buffer.
