Packet Radio

• aka “that weird AX25 kernel module that I never compile”

• Multiple connections on the same frequency

• Has error correction and handshaking

• Can send messages to BBS and repeaters

• No longer needs expensive external TNC box; can operate through sound card.

Notes:

HERE BE DRAGONS: I don't use Packet, and only know one person who does. It was pretty popular before wireless became what it is today.
