[Tinyos-help] Problem with Listen.java

[Michael Schippling]

Looks like you may not have installed the serial comm jar and library.
Usually I would say, find javax.comm
(I have it at: http://www.etantdonnes.com/TMP/javacomm20-win32.zip)
but this looks like it is using the new-improved TOS version TOSCommJNI.
I don't know where that is, but a quick google may help...
