Subject: Discard too short log lines
X-Git-Url: http://git.itanic.dy.fi/?p=log-plotter;a=commitdiff_plain;h=5b5bb6500af4523d153306590d24032552cc17ed;hp=7392d1212f17b998364f8499ce8c6e0fb65fbb5a

Discard too short log lines

Some times the serial output contains incorrect entries, typically in
the beginning of log acquicition. Discard them so that they don't
clutter the log output.
