[noPoll] pelase help, about tls

[sumin en trus.co.id]

Hello Francis

thanks for your information

why do i get wss "client hello" packet (3 first bytes are 22, 3, 1)  
from nopoll_conn_read? (blocking socket)
do i miss accept/handshake?

note : on previous mail, i said wireshark didn't capture client hello, 
it turns out client hello was sent but wireshark didnt label/recognize 
it as client hello

Regards

Su Min
