I've recently had a problem when first booting my PC & DMC-4040 controller where the TR (trace) command is automatically started. I have a medium sized program burnt into the controller using many threads that gets started automatically at power-up. My system is setup for developing and updating/debugging my Galil program. I have an ethernet and serial cable connected to the DMC. The fact that the TR command gets started automatically causes problems trying to connect to the DMC due to the heavy traffic on the communications port. I manage to establish connection by turning on the DMC and quickly starting GalilTools and pressing the Connect icon and selecting the serial connection. I then turn off the trace (TR0) and everything is fine after that - until the next reboot/power cycle. Any advice would be greatly appreciated. Thank you.
