Recent photometry and spectroscopic data leads support to the
 theoretical expectation that some M dwarfs have stellar winds
 several orders of magnitude greater than the solar value.
 If so, the wind is expected to have a power-law spectrum. Present
 observational data from IRAS, JCMT and the VLA suggests such a spectrum,
 for several active dwarf M stars. The major problem with this data
 is its poor quality above 25um, and for many M dwarfs only upper
 limits are possible.

   ISO photometric and spectroscopic data can improve this situation,
 and combined with new millimeter data with SCUBA on the James Clerk
 Maxwell Telescope (JCMT) major advances are expected. Confirmation of
 this power-law spectrum has important implications not only for evolution
 and interstellar medium physics but also whether discrete magnetic
 events such as coronal mass ejections can contribute to the coronal
 dynamics of active dwarfs and thus to their mass loss rates.
