Thanks for the encouragement to do more "digging". I now know the RS232
interface is made with the SP232A. (I did not realize there are Rxd and Txd
pins on the 68HC11. I did not have the "eyes" to see.) The code for sending
the data is a "3 liner", simple as you said. Everything works just fine.
Good to have this group of people to communicate with.

I find it easier just to write my own routines. Handling the SCI
is pretty simple.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
