I've used various serial devices, including UPSes, via various
USB-to-serial adapters (Prolific PL2303 and FTDI FT2232C), and all the
signaling works fine.  Only issue you sometimes have is that there are
many cheap adapters on Amazon that claim to be Prolific or FTDI but are
in fact counterfeit clones - those may or may not work reliably for ANY
purpose.
