Forum: IronRuby can't convert Fixnum into String (TypeError)

This program works with ruby and jruby but it does not work with iron
ruby. I get the following error:

multi-client-tcp-server.rb:29: can't convert Fixnum into String
(TypeError)

I'm new to ruby. Can someone help me fix this so it will work with both
ruby, jruby and ironruby?

Thanks!
Siegfried
