Features And Capabilities
JavaTerminal (or Java Terminal) is a
simple TELNET Bulletin Board System client written in Java which
focuses on rendering rather than a full TELNET or ANSI X3.64
implementation. The two available protocols are TELNETBBS and
ANSIBBS which are both subsets of the their respective protocol
specifications. The goal of the project is to make available a
simple and good looking client implemented entirely in Java. If
you are
interested in seeing new features added or participating in the
project, please follow the SourceFORGE Project link at the top of the
document.

Keyboard
Most key sequences are sent "as-is",
including control characters (such
as Control-A).
However the following keys have special interpretations.
Mouse
The first left click will select the first character
and place it immediately in the clipboard. A subsequent left
click while holding down the SHIFT key will add that character as well
as all characters between the
first and last into the clipboard. Another way of doing this is
by left clicking on a character and holding down the mouse button while
you drag the selection highlighter.
Right clicking the mouse will paste any character text clipboard content into the output buffer as though it was typed. This copies what is on the system clipboard so copying from another program will work as long as only text is found in the clipboard.
Also the mouse wheel will scroll the screen view by an amount predefined by the Java runtime environment.
However the following keys have special interpretations.
| Page Up |
Moves the scrollback view up one
page. |
| Page Down |
Moves the scrollback view down

| Arrow Right |
Character Discipline:
