[Ekiga-list] text chat

[Wayne Ye <wayne ye23 gmail com>]

Hi all,

I have some questions about the text chat in
gnomemeeting(1.0.2) and openh323(major version 1 and minor version 13).
In that version it has a userinput capability.

The characters
input by one user is transmitted through functions: SendUserInput ->
SendUserInputIndicationString -> WriteControlPDU -> WritePDU
-> TCP Write. 

And then OpalLineChannel::Write()-> WriteFrame? Is that right?

Another question is: Is the text transferred using the audio channel? Because I did not find a unique text channel or userinput channel like audio, vedio channel and the WriteFrame function also contains audio choices.

Thank you very much,
Wayne
