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.
