title: Need a good serial port logging tool
body: <p>I'm working on an embedded system and it uses one serial port for all it's logging purposes.</p>
  
  <p>Is there a tool out there that allows you to filter lines into different windows (or remove them altogether) so that I can separate the output of the various logging sub-systems and remove spam messages that show up multiple times a second?</p>
  
  <p>I'd prefer an open-source solution, but a highly-recommend closed product might do.</p>
