Hi all.

Could someone tell me or appoint me a code
to make software USART. I�m using a 16F819
in a project, but I need to send some data to
RS232 port.

Check the example files EX_PBUSM and EX_PBUSR in the PICC\EXAMPLES directory this should give you a good start.

#USE RS232 (see manual), if your PIC does not have a hardware port , the compiler will create a software one , works great with PIC16F676 !!!!

Tks for reply JFK.

But my project uses 16F819 chip.
The #use RS232... fuse will not work.
I know I will to read/write bits to pins
at hand, but I can�t figure how.
I�m a begginer in PIC programming.

Why does USE RS232 not work on the 16f819?
I'm a newbie to RS232 myself so not best placed to advise you.
I had USE RS232 working on a 16f818 and 16f737 recently it should work ok on all pics as far as I'm aware.

It won't work on it's own you need to look in the user manual and read all related topics to the USE RS232 command.
