no luck with Force mode

Conducted another test in Backyard EOS with the custom mirror serial cable (based on Beskeen's design) using the TV mode. This time I had the Camera Force Use Serial Cable setting turned on. No difference. At the end of the run, the software was slow, the camera could not be properly controlled. The mirror cable status of red (vs. yellow) showed the serial port was holding the shutter closed.

Guylain asked for the log files. I sent them in. He spotted a number of "device busy" errors.

He said he had a 40D in his collection. He said he was going to try it with his DSUSB cable.
