  This same machine with Ubuntu 11.10 works Ok. with the Prolific USB to
  Serial converter. I changed (whit a new install) to Ubuntu 12.04LTS,
  and this converter and Fldigi (last update) will not comunicate.

  Please help me. I like Ubuntu, but can only make digital comms. with
  the Mac OSX 10.8 or Windows.

  Thanks
