Hello everybody,

After many search, I hope find here a solution to my problem.

I'm using the PIC16F877, and I would like

1) Receive a byte through USART interrupt,
2) During these interrupt sendback a byte with the usart.

The first point here above can be esaly done, eg :

But how can I perform the 2nd point because the HSERIN and HSEROUT command are not available in case of using the hardware serial interrupt???

May be by using the simple software serout command, but is not the realy best method.....

WKR, thony
