Hi everyone, I just replaced a SmartUPS 1000 with a brand new SU700. The 1000 was visible to my Linux RH6.0 machine, running PowerChutePlus 4.5.2 software. It was set-up for ttyS0. I could remotely test and monitor the UPS. After the switch, I am getting the following error when running Config.sh: The following Port validations for /dev/ttyS0 may take a few moments.... /dev/ttyS0 appears to be a local control port ---------------------------------------------------------------------------- WARNING: Could not communicate with device on /dev/ttyS0. Check that the communications cable is attached properly to both the device and the serial port. ---------------------------------------------------------------------------- I am using the first of two available com ports. I tried two shutdown cables, one of them was working on that machine this morning. When I run statserial for ttyS0 I get the following settings: RTS 1 CTS 1 DSR 0 DCD 1 DTR 1 RI 0 Would any of you have any suggestions on how to further troubleshoot that problem? TIA.
