*OSI layer 2 (data link layer) protocol. Technically, it occupies layers 1-3.
*Same layer as BATMAN-Advanced.
*Used for packet radio by hams.
*Can transport network layer protocols.
*Not designed to support switching, though routers can probably be set up to handle it.
*Support in the Linux kernel.
**v2.6.x: ax25.ko
*Commonly used with three different communication specs:
**Bell 103 tones @ 300bps
**Bell 202 tones @ 1200bps
**G3RUH DFSK @ 9600bps
**These speeds are hard limits.
*KISS encapsulates frames such that they can be send to a TNC for transmission. Derived from SLIP.
*KISS is a serial protocol. Thus, multiple serial channels are required for multiple transceivers.
*Other protocols fulfill the same function.
