Client Sync Problem

Have sync a problem. Tried testing the sync servlet using the URL http://<SERVER>:<PORT>/meSync/servlet/meSync?_sysid=NSP&login=<USER>&_{password=<PASSWORD>&}client=000&_language=EN&acknowledge=X&~test=true&

and the result is

&WAF_SYNC&STATUS=A&Execution Time= & HeaderType = MEREPLICATION &MORE_PACKAGES_WAITING = &

What does "STATUS=A" mean?
