is it possible to set green point in user's client from server? its possible from client but.

i did try 0x56 packet but there should be item map etc.
so if someone know then please
question[2] := regard 0xC8 packet
i use HSA client. at fist time server said that unknown packet c8 and character stuck after some steps.
from packet description i should send it back. "If and only if erver "relays" the packet (sending back the same data) range stuff gets activated client side."
i had create receivefunction and do this:
var pol_packet := CreatePacket(0xC8, 2);
pol_packet.SetInt8(1,18); ///packet.GetInt8(1)
pol_packet.SendPacket(character);
after this server dont say that unknown packet but character still stuck and cant move after 8-9 steps.
what i do wrong? or maybe the reason in some another
