You don't need SatStat.  (or a Windows environment)

I've done it on Linux with roughly the following recipe:

use stty to setup the serial port parameters

on one window:
cat /dev/ttyS0

on another window
echo ":SYSTEM:STATUS?" /dev/ttyS0

I forget the command and format for setting the date.  The details are in the 
Z3801A manual.  (I can't find them in the 59551A manual.)
