_______________________________________________________
Details:
This recent modification to sockets.c looks problematic:
227 /* TCP sendbuf is empty, but not connected yet, so not yet
writable */
228 sockets[i].sendevent = (newconn->type == NETCONN_TCP ? 0 : 1);
However, sendevent appears to be only set by NETCONN_EVT_SENDPLUS, and that
is only generated from sent_tcp(), err_tcp(), do_close_internal(),
do_connected().
Shouldn't sendevent be raised on accept() as well? What should a server do if
it listens and accepts a connection and then wants to write to the socket?
