Gday Logan
PHD can output pulseguide data via USB to serial to the mounts rs232 port if it has a valid driver inbetween ( normally an ASCOM driver )
PHD can also output low level ST4 commands directly to the mounts ST4 port if you have a suitable USB to ST4 converter/cable. In the latter, no ASCOM driver is required for guiding, but you only get guiding.
