[Tinyos-help] b6LoWPAN - telosb - IPBaseStation - serial_tun - problems

[Stephen Dawson-Haggerty]

Hmm, I've only seen that rarely on my Thinkpad; I've always thought it was a
problem with the usb/serial driver, or maybe some wierd hardware thing.  It
doesn't happen on my workstation.  Maybe it's a vmware thing?

Sorry I don't have a better idea,
Steve
