When you say you can't connect over COM1, are you using the developer jar (just downloading jempeg-0.9.14.jar) or did you use the actual installer... If you just grabbed the jar, you will also need to get javax.comm (the serial port communications api). If you used the installer and it still does not work, then I'll look into that one further... Could be a problem with javax.comm on w2k.

Thanks for trying it out...
