If a man replies the question "What are you doing?'"
with,

1. GELIYORUM, it means that he is in the act of coming straight over, with no planned intermediate stops in between,
2. GELMEKTEYIM, it also means that he is on his way, but implies that there are intermediate stops (secondary chores, stopovers etc.) in between.
