It's like HyperTerminal, but not shitty and annoying!
This is a Java app, written for JRE version 6. It requires RxTx, a free serial comms library for Java on Windows, Linux, Mac & Solaris. RxTx is not packaged with this application - you can grab the latest binaries here. (The zip contains an INSTALL file which explains where to put everything on each platform. You must do this before running CrapTerminal.)
3 (1 Oct 2010): Backported a bunch of changes from Iridium9601Sim. Ported it to use RXTX not JavaComm.
2 (26 Feb 2009): Fixed the printing-one-character-every-two bug, Added ability to send.
1 (21 Aug 2008): Initial release.
