Talk about off-topic: Us hams used to do a lot of passing programs around
by radio. Packet radio, loosely based on AX.25, is a 300 or 2400 baud,
error-check-and-retransmit protocol that is used for mail, bulletin
boards, and transfer of... ...darn near anything. Typically used VHF or
UHF on ham-only frequencies, e.g. 144 to 145 or something up in the 430
mHz area, popularity fell off quite a bit in recent years, until the
advent of APRS.

APRS is automatic position reporting reporting system, which is send using
packet radio. A small handheld radio, a GPS or GPD chip, and a packet
controller or controller chip, allows a public safety vehicle or event
vehicle's location is constantly updated on all maps monitored by event or
rescue coordinators.
