[Tinyos-help] Problem with USB-to-Serial Cable for mote-pc communication

[Yu (Jason) Gu]

Hi,

I'm using tinyos 2.1.0 on Ubuntu Hardy, micaz and mib510. I can burn the
image to the mote with my usb-to-serial cable without any problem. However
when I tried to connect to the serial port with SerialForwarder or other
java applications, I got following error message:

serial@/dev/ttyUSB0:57600 died - exiting (java.io.IOException: Could not
open /dev/ttyUSB0: TOSComm JNI library runtime error: get_modem_status:
Invalid argument

I have checked and made sure the port /dev/ttyUSB0 is world writable.

Any potential solutions to solve this problem?

Thanks,

Jason
