ARPANET Network Control Program for Linux, interfacing with the SIMH IMP emulator.

This is a work in progress. At this point, the NCP is not a high quality implementation. It's primarily used for testing the network.

• Implement the IMP-host interface.
• Exchange 1822 NOP messages between host NCP and IMP.
• Send ECO message to another host, get ERP back.
• Application library for NCP.
• Send RFC and CLS messages to open and close connections.
• Send data back and forth.
• ???
• Profit!
