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
