Pulled a never used RioCar off the shelf (v1.x firmware). Wired it up on ethernet and serial.

jemplode 45 (launched from full install executable .exe with integrated java environment) could see it on both serial and ethernet. However, I let it try to do the initial handshake for more than an hour and a half before telling it to give up.

jemplode 45 (launched directly from jar file with most recent Sun JVM) couldn't see it on serial at all.

jemplode 54 (launched from jar file with most recent Sun JVM) couldn't see it on serial at all.

I used emplode to upgrade the unit to v3a7 final (developer image). Then I used upgrader.exe that came with the Logo Editor app to install the hijack kernel (whatever today's release version is!).

Now both jemplodes can see it and interact with it on serial...doing an upload now (and all night) with v54 under sun's jvm.

Not sure what the integrated vs. sun jvm issue was, but it also appears that Jemplode also had an issue with v1 empeg firmware. Known issue?
