Framebuffer update request

[ankit]

Hi All,

I am implementing my own vnc client just for the fun of it and to learn
about the protocol in more detail.

So far i have reached the point where i send the FramebufferUpdate request
to the server ( i requested a non-incremantal update toa 50x50 pixel box).
however the server does not reply to this.

So i fired up realvnc client and examined the packets using wireshark and it
seems that the client sends multiple framebufferupdate requests
before it gets its first framebufferupdate.

1.So do i need to send multiple requests to the server to get the first
reply ?
2. for the sake of simplicity in the setencoding message i just use RAW and
COPYRECT. would that make any difference ?

Thanks
