Thanks, Chris.
Well, I was completely wrong in my thinking about internet satellite service.
I have been an amateur radio operator since 1954, and we can routinely use satellites for 2-way communication.
It is even possible to bounce the signal off the moon, down to the other station, although the moon is not a very good reflector of radio energy.
Meanwhile, back to the subject, I always thought the internet satellite service was 1-way, and some other technique like the telephone was required when you hit <enter>.
Your explanation is very much appreciated.
By the way, the forum has seemed to be a little slow the last few days.
