    Maybe it would be better to try "nut-server" which could have a
    better apcsmart driver implementation?
    I have APC SmartUPS SC1500I with similar setup, USB-to-COM adapter
    and self-made APC UPS Smart cable and it is working fine with
    nut-server, both monitoring and control.
    
    Another thing to check could be an usb-to-serial adapter. I've seen
    some cheap low-quality adapters which were created with counterfeit
    ICs.
