Activesync looks at the serial port for any activity. If it sees that activity it fires up in the background and attempts to connect. That connect process has a high priority in the operating system, but normally only takes a very short time to connect, so you don't notice it.

Along comes GPS, provides activity at the port. Activesync starts to do it's thing, but doesn't connect. Unfortunately, that same high priority now is being spent on an activity that will never end, so the Ax slows to a crawl until you disconned the cables and A/S gives up.

To prevent this activity, start the software on the Ax first, get it searching for the GPS signal and THEN AND ONLY THEN, connect the cable to the GPS. This sequence blocks A/S from seeing the activity on the port and firing off.

4800, N, 8, 1 is the protocol to use.
