Since moving to Toolkit V1.15.7 Build 2473, with C-Gate V2.11.5 Build 3260 I am unable to access my PCINT4 FW 4.4.00 unit, Toolgate reports that the "PCI Failed to reset". If I use a much earlier version of Toolkit and C-Gate I have no issues. Using the C-Bus Diagnostic too, again no issues. A Serial Port Monitor sees the traffic, but it seems to have additional noise coming from the network, not present using Diognosti Tool. I wonder if the COM port (a real physical serial port) is being opened at either wrong baud rate or parity. Has anyone else seen this or am I the only one. I do have two USB interfaces available, so not a disaster, but I don't want to be beaten :) Thank you Simon
