You are correct in your first thought. I have an application using the the reverse method working fine. But I am connection to a source that allows only one connection. I tried the IO::Select idea. but it seems to block on every client but the one.. am I just missing something or just totally lost. I am trying to get this to work on a Win2K platform. any help would be great. Just enough so i can get my information to all the clients at the same time. I am slowly running out of hair on this.. and so is everyone else
