Plugin no longer working after update to 6.0.6

EDIT: I have just seen the remark regarding serial communication affecting the DSC Plugin. I have performed the workaround suggested and can confirm this also helps with the RFXCOM Plugin.

I updated to 6.0.6 this morning and now the plugin fails to send commands to my Intertechno switches.

RFXCOM Debug Turn ARCAppliance Appliance/Dimmer On (level 0).
RFXCOM Debug Adres: 1
RFXCOM Debug housecode:C
RFXCOM Debug device type:ARCAppliance
RFXCOM Debug device type:1
RFXCOM Debug send x10 cmd: 7 16 1 7 67 1 1 0 (07 10 01 07 43 01 01 00)
RFXCOM Error send "Shed lights" on failed

these were working until I upgraded.
The Oregon sensors are detected as before the update

Is a download of 6.0.5 available anywhere so that I can go back to a working system?
Is the plugin still being supported? The bug I reported a while back concerning the battery status no longer being shown has not even been commented on.

Hi Tim,

I'm having trouble tracking down the exact reason this is failing. I know it is related to an update to the serial library, but I cannot reproduce it. A couple of questions:

1) Are you connecting to your RFX module directly via USB to your Mac?

2) What version of Mac OS X are you running?

This problem should now be fixed in Indigo 6.0.7.

Hi Matt,

I have updated to 6.0.7 and everything works fine.

Perhaps no longer relevant but to answer your questions:
1. Yes directly connected via USB
2. Mavericks OS X 10.9 (13A603)

regards

Tim
