Re: TI-H: somthing hardware related for a change
No one has taken the initiative to build one. You can get RF data transmitters
and receivers for about $10-$15 each (prebuilt, etc).
You can use one wire to control whether the unit is sending or receiving at a
particular moment, and the other as a data channel. Everything else would be
done in software. It would take a bit of work to get it going in an ASM
program, and current programs would have to be adapted, or someone would have to
create a driver that essentially cuts in for TI's cable communications.
Alternately, one could use a microcontroller to emulate a regular wired link
connection with these two readio modules, using some buffering and intelligent
switching. This would be more compatible with the on-calc routines for cable
communications, and a mode could be selected to make it work for those ASM
programs that don't use TI's routines.
The crux of the matter is that they both require hardware and software
knowledge, and only a few people on this list do both really well. Those that
do have little interest in a radio link.
If you want one, learn what you need to learn to make one yourself. Someone
eventually has to decide that it's worth their time and effort, and if it's not
you, then who?
