Open Bench Logic Sniffer / Linux issues with 0.9.6.1 client
I am running Fedora Linux (Fedora 18, currently a 3.9.6 kernel on a x86_64 system).
I am running Java 1.7.0_25.
What I am seeing is that I cannot run the client as myself (user tom),
but it seems to run fine when I run it as root.

I changed permissions on /dev/ttyACM0, first by hand, and then by putting this file in place as
 /etc/udev/rules.d/51-ols.rules  ---

# UDEV Rules for OLS logic sniffer
# The game here is to get permissions we might like,
# and to tell modem-manager to drop dead.
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="fc92", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="fc92", MODE:="0666", NV{ID_MM_DEVICE_IGNORE}="1"

Even as root though, the button to "Show device metadata" does absolutely nothing.

And as myself, I get:

java.lang.IllegalStateException:
JTermios call returned -1 at class jtermios.JTermios$JTermiosLogging line 489

 at purejavacomm.CommPortIdentifier.open(CommPortIdentifier.java:138)
 ...
 ... and much more ....

Open Bench Logic Sniffer / Improper signal inversion
I am two days into fiddling with the logic sniffer v 1.04 that I got earlier this week.  I am using Jawi's 0.9.6.1 client under linux
(Fedora 18, a 3.9.6 kernel).  I am looking at signals from an old MC68010 cpu board.  In particular, I am monitoring
HALT* and RESET* (both are active low), and I set up a trigger on reset to do a capture when reset transitions from low to
high (and this works perfectly).  What is truly odd is that the capture shows both of these signals transitioning from
high to low, which is exactly wrong.  A meter shows RESET* as 5.0 volts when the CPU is running, which is as it should
be, but the sniffer shows this signal as a low.  The fact that the trigger worked properly is certainly in conflict with what I
see on the display.  Anybody ever seen anything like this?
