Timing issues with 2412U insteon powerlinc modem

Folks,

One small issue that I have seen with the 2412U is that receiving modules may lockup if you turn on/off the same device too quickly.  I have my X10 Chime plugged into a ApplianceLinc (firmware revision 2.8), since my 2414U lost X10 functionality. (Please note, that this loss of X10 functionality is a known issue, at least PerceptiveAutomation knows of it.  I don’t know if SmartHome recognizes this as an issue.)

But, I had to tweak the timing on the ApplianceLinc, because if I turn it on, and then rapidly turn it off, the device seemingly becomes stuck in the off (or on) position, and silently fails if you change it’s state.

Do I consider this an 2412U issue?  Not really.  I believe that the ApplianceLinc’s firmware is the root issue, and that the speed of the 2412U just exposes this issue.  I have tested this with ApplianceLinc’s running firmware v2.8 & v3.2.

Does anyone have a firmware that is higher?  Or seen any other issues?
