Two options here:

1) edit source code, replace 3003 with 3004, see what breaks

2) connect up the Windows software, capture some traffic, help debug
the resulting changes to the driver.

In either case, make sure that the equipment plugged into that UPS is
not critical.

It's a sad state of affairs, but that's what appen when the
manufacturers keep their protocols proprietary.
