Dear Ladies and Gentlemen, I have several old, yet functioning APC Smart-UPS (Model 600LS, Part AP600I, Firmware 6JI, no EEPROM, from 1991). They are not supported by Powerchute any more. I run NUT 2.6.5-4 on Windows XP SP3. I use COM1 port with cable 940-0024C. The connection fails with APC Smart protocol driver 3.0 (2.6.3-3534:3540M), APC command table version 3.0 or higher - it works with APC
