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.
If you have a question, please first read the FAQ. It's kind of a pathetic FAQ file for now, but I bet your question is in it!
Both Michael Tautschnig and Jonathan Liu reported minor problems with the software. Michael correctly spotted a data type error in the handling of crc8 calculation and Jonathan asked to increase the interface name and alias length. A new version 2.1.2 is out fixing both problems. Is it a coincidence I've fixed both problems a month after receiving the reports and a day after receiving my second real postcard? I'm afraid not, bad me, bad me!

Just today received my second real postcard. All the way from Aotearoa, New Zealand!
Thank you, Johan, Lipi, Chris, Nigel, Shregas, Bwce, Werner & Barny, for reading the README and acting upon it. It has put a big smile on my face! Please forgive me if I have misspelled any of your names.
Below is an example of the output one can see when reading from two serial devices at the same time:
$ jpnevulator --ascii --timing-print --tty /dev/ttyS0:SB9600d --tty "/dev/ttyUSB0:Motorola MTM800" --read 2006-05-30 13:23:49.461075: SB9600d 00 00 05 3B 0D 00 00 05 ...;.... 2006-05-30 13:23:49.461113: Motorola MTM800 00 05 3B 0D 00 00 05 3B 0D ..;....;. 2006-05-30 13:23:49.473074: SB9600d 3B 0D 00 00 05 3B 0D ;....;. 2006-05-30 13:23:49.473105: Motorola MTM800 00 12 05 06 39 00 12 05 06 39 1F 00 22 80 00 0E ....9....9.."... $
