Nice serial sniffer and you can use it to send data on a serial line too [[http://jpnevulator.snarl.nl/]].

== Slackbuilds creation ==
The SlackBuilds is created based on the instructions available in [[http://www.slackwiki.com/Writing_A_SlackBuild_Script]].

Run commands:
{{{#!highlight sh
APPNAME=jpnevulator
SOURCECODE=jpnevulator-2.1.1.tgz
cd /tmp
mkdir $APPNAME
cd $APPNAME
wget http://jpnevulator.snarl.nl/download/$SOURCECODE
touch $APPNAME.SlackBuild
touch slack-desc
tar -xzf $SOURCECODE || exit 1 
nano slack-desc #fill slack-desc
nano jpnevulator.SlackBuild #fill jpnevulator.SlackBuild
chmod 755 $APPNAME.SlackBuild
./$APPNAME.SlackBuild
installpkg /tmp/jpnevulator-2.1.1-i486-1_SBo.tgz

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in.  You must make
# exactly 11 lines for the formatting to be correct.  It's also customary to
# leave one space after the ':'.

jpnevulator: jpnevulator - Just another serial sniffer
jpnevulator:
jpnevulator: Nice serial sniffer and you can use it to send data on a serial 
jpnevulator: line too. It's sort of like a very simple terminal emulator, like 
jpnevulator: picocom. But jpnevulator uses hexadecimal byte values to display 
jpnevulator: and send along the line. Very handy indeed if you are working a 
jpnevulator: lot with serial protocols.
