It's been a great discussion and a real eye-opener for this naive
academic, who assumed that USB is properly regulated by an IEEE
Standard [it is not]
and that a well-engineered, standard-observant and portable USB driver
exists. [It doesn't.] Thank you all for helping to set me straight!
The takeaways for me:
*There is presently no feasible alternative to RS 232 as an Interface.
Wayne & Eric made the right choice. USB is a non-starter, being FUBARd
due to the lack of an enforced standard. What's more,
* RS 232 is plenty good enough for the undemanding radio control or
"knob-substitution" task. [Audio & video transmission may be another
matter, but that's for another time.]
* There's no call to sniff at RS -232 just because it's almost a
half-century old. Unix [tm] is about forty years old, and still the
reliability and efficiency champ.
[No, I don't want to start a controversy on that!]
* Desktop PCs are better than laptops for radio control, because you can
fit RS232 cards to them. And laptops may have noise problems due to
sloppy construction.
* There are many - way too many - radio communication protocol
"standards" - Kenwood, K3, etc etc. We must just Get Used To It
[until YaeWoodCom sees the light and imitates the K3].
