[Tinyos-help] Invalid port. No comm ports found.

[Michael Schippling]

OH, your first message had COM1 in the MOTECOM and COM3 in the error msg.
As I and others have said, make sure you have your mote plugged into
the correct port and have the right name for it. I always set the MOTECOM
with the export command and then just do:  java program

Of course "COM" only works on Windows, if you're on Linux the port names
will be different. It may be that you need to use something like:
  "/dev/ttyS0"  (in the case that you are attached to COM1). If you have
a USB->serial adapter the names will be wildly different as well.

I'm guessing you have mica motes since I believe hardware_check doesn't
work with telos types. I further believe that "motelist" only works
with telos. I stand to be corrected on both those assertions.
