DigiConnect Me w/o virtual COM ports

Hi!I’m trying to directly communicate with a serial device which is connected to the DigiConnect Me ethernet adapter. The DigiConnect is configured to allow raw tcp/ip on a custom port. However, when I open a plain TCP/IP socket connection to the DigiConnect and send some data, nothing seems to be passed through. Could I be missing some obvious configuration settings ? The telnet compatible pass-through mode also seems like a viable alternate. Is there maybe an open library that can be used to handle the handshaking that takes place upon opening a telnet connect and to escape/unescape data that is to be passed to the serial device ? Thanks, -Markus-
