Unable to Use Telnet Because Firewall is Blocking "System"

RalphMalph

I am trying to use a telnet connection between a custom app and a terminal emulator and Sophos Firewall blocks the connection saying invalid checksum for "system".  I have no idea how to add a checksum for "system".  What is this trying to tell me?

    Why is interactive mode not available under Win 8?  Will this be offered in the future?  What about Win 8.1?  I am thinking of upgrading to 8.1 but it appears that support by many apps is limited just as your support for Win 8 is somewhat limited.
