And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.

I have tried that already, in this fashion `recv(LINK_HNDL, $temp, $size - length($data),MSG_DONTWAIT);` can you tell me, if the usage is incorrect? I am getting following error message "Your vendor has not defined Socket macro MSG_DONTWAIT, used at tb_data_lnk.pm line 234." I am using perl version v5.8.8 built for MSWin32-x86-multi-thread, this is active perl. I have some more observation, like before perl control reaches recv function call, if i switch of the server(board), recv function was not behaving in a blocking manner. but during the perl is waiting on recv function, if i power off server board, it is not coming out of the recv function call	[reply] [d/l]
