jpnevulator

This is the homepage of jpnevulator. What once started as a Jackpot Navigator emulator (hence the strange name) is now a nice serial sniffer and you can use it to send data on a serial line too. It's sort of like a very simple terminal emulator, like picocom. But jpnevulator uses hexadecimal byte values to display and send along the line. Very handy indeed if you are working a lot with serial protocols.

jpnevulator is released as Free Software under the GPL license. See the file COPYING in the source tarball for more information.

For your convenience you can find the manual page here. If after reading it you have a question, please next read the FAQ. It's kind of a pathetic FAQ file for now, but I bet your question is in it!

News

These are the (max. 10) most recent news items about the project:

08/02/2019-Is this piece of software finished, like I thought it was in 2011?
More than some years and not much happened. The casual observer might conclude that this project is dead. Well, it's not dead. It's just that I think it's finished for now. I haven't used the program a lot in recent years, but I have always been happy in how it worked. Nothing to improve. But if you feel different, please let me know. :)
I've said something alike this before, back in 2011 and a lot has happened after it. To my surprise a lot of people still use my software. Let's see how goes this time. Please don't forget to send in a postcard. It's much appriciated!!
