These are the things to do to configure apcupsd to a legacy APC UPS using a 940-0024C Smart Serial Cable,
2. Minisys BIOS = Disable COM redirection. In Addition I set mine for 2400,n,8,1 or whatever speed ur UPS is currently set.
# RJ45 DB9-M
# 3 ----- 1
# 6 ----- 2
# 5 ----- 9

UPDATE: Even Simpler. Use an USB-Serial dongle like the popular Prolific PL2303 which FreeBSD 11 has built-in driver, coupled with 094-0024c will do it. Then u save the 1 com port for console use. Mine came up as port cuaU0 (uppercase U) when hooked up to the USB3. So config DEVICE /dev/cuaU0.
