All, Thanks for the assist. We had an engineer in to deal with a VTS problem, and asked him to check the convienience.
There turned out to be a piece of plastic from a cartridge which had become detached causing the sensors to fail, leaving the robot in output mode. This is now sorted. Thanks again. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
