Re: A89: RE: Radio link protocol : Use the one that's already THE standard in computers.


This is getting really stupid.  Pirate radio stations and talk of Ham radios.
This is a calculator list!
Anyway, a "ham" radio is short for amatuer radio.  You must be LICENSED to use
these bans and radios although anyone can buy one.  There are major jail times
and penalties even for the shortest range "ham" units.
Packet radio, using a tnc has been going on for ages, since the ages of XT
computers for communicating to local BBS services without making a phone call.
It has fallen into disuse.  The point is, not everyone can just start using it,
and for any task they feel like.
Anyway, this isn't something you want on your calculator.  Although it works
with a standard terminal program connected to a serial port, the device is big.
Picture a big external modem.  And the radio gear to use it is just as bad,
unless your the type to always carry a 2 way radio.
I don't claim to understand all this stuff, but a good friend of mine hada setup
and I questioned him about 5 years ago to see what it was all about.
