+Netrom over TCP Support
+
+This is intended for operation over radio links with an IP interface, eg New Packet Radio or possibly microwave links
+
+To simplify interface to the rest of the oode dummy LINK and PORT records are created
+
+Packet Format is Length (2 byte little endian) Call (10 bytes ASCII) NETROM L3/4 Packet, starting 0xcf (to detect framing errors).
+
+A TCP message can contain multiple packets and/or partial packets
+
+It uses the Telnet Server, with port defined in NETROMPORT
+
+ROUTE definitions have an extra field, the TCP Port Number
