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!
|28/07/2020||-||Release of version 2.3.6|
Not much of an interesting release. A small potential buffer overflow and some spelling errors fixed. The FAQ updated and that is mainly it. A bit boring, but here it is: version 2.3.6.
Might be nice to add though that after a couple of decades after industry standards this software is also finally digitaly signed. It's about time! Kuddo's to Debian for nagging me about it.
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.."... $
