chardev: Basic support for TN3270
This introduces basic support for TN3270, which needs to negotiate three Telnet options during handshake: - End of Record - Binary Transmission - Terminal-Type As a basic implementation, this simply ignores NOP and Interrupt Process(IP) commands. More work should be done for them later. For more details, please refer to RFC 854 and 1576.
