oha,
1 ms for Data transfer is way too much. And recieving data (no sending!) in the background seems the only thing to do

In my picbasic pro book from Dogan Ibrahim it says " USART is very complicated"
and that did not encourage me.
Because I use only 16F628A , maybe with 10Mhz that should do.

How could I use the Usart . I think those 16F628A have one....
