I try to control the 32ch ethernet board, but the module always refused my connection. With terminal emulator or web browser the board work perfectly, according user manual. When I control by software the connection is ok, my program receive the module welcome message and ask the user. I sent admin to the module. The module ask Password: ˙y' after the sending of admin the module answer acces denied massage and disconect the connection. I do not use any protocol I send only the accii commands regarding manual with CRLF. You have any idea what do I wrong? What are the ˙y' not ascii characters in the module message?
