i just bought a new pulseworx pim AND upgraded to the lastest upstart version on the sai home page. now when i try to use upstart to get status for program devices i find that the connection from my pc to serial pim drops out. i use a usb/serial driver to connect from my usb port via usb/rs-232 cable to my serial pim. never had this problem before anybody else experiencing this kind of problem?
