However, when you type /fsend on (you have to be the one who sends), this confirmation isn't needed anymore, and mIRC will just keep sending packets, regardless of any confirmation being recieved (you can even see this in the progress bar).
this is not totaly exact.... sometimes you'll see pause in dcc transfert, it is because mirc didn't received acks pro some packets and don't have free buffer to continue to send. with fsend on, mirc doesn't wait before sending next packet IF it has free buffer. a buffer is free if 1) it has not yet been used, 2) it has been send and the ack received. how much buffers use mirc ? for what i know it is a matter of 32k / dcc packet size of something like that or maybe it is fixed to 8 by dcc... ( i do remember this 8 limit when i did some tests but ... oh well it's been a while
)
