Download (precompiled for Java 1.5, or the source) a Supdup-enabled version of the Java Telnet application. The original code is fairly easy to add plugins to, but so far I had to hardcode the use of the supdup terminal emulator, so this version is only useful for Supdup.
?? 2009-04-05 :: handle MacOS X Escape key and Control-Space, and supply a [[http://victor.se/bjorn/its/Supdup.dmg|MacOS application]] ([[http://victor.se/bjorn/its/Supdup-app.tar.gz|.tar.gz]]). (The Alt key doesn't work yet.) !! ?? 2005-08-10 :: avoids idle (logged-in) disconnection by periodically sending a "keep-alive" to ITS. !! ?? 2005-08-06 :: supports the [[http://up.update.uu.se/sailch%20html|SAIL character set]]! Thanks MMcM! !!
To run, use
java -jar supdup.jar [hostname]
Note that the window can be resized, but the change only gets through to ITS at connection time (due to the Supdup protocol). Note also that you can use Ctrl+X for non-alpha X, e.g. digits, at least in Linux - it doesn't seem to work in Windows. Note also that you can use it as an applet, if your Java sandbox allows.
