I think it is looking for bytes so you could change you writeChar to
writeByte and that should work but if you are sending only String
data then I think that using a PrintStream is much easier. for
instance
.... Previously create MySocket.....
PrintStream psOut = new PrintStream(MySocket.getOutputStream());
psOut.println("Send Me");
That will send a string that can be read with readLine on the other
end.
As far as the EOF is concerned I would assume closing the connection
should result in an EOF but I am not sure.
Hope this helps,
Walt
