interrupt with rs232 on a 16f877 chip

[maddog]

hello

how do i have to config a interrupt which is triggert on the rs232 so it interrupts when something receives on the rs232.

which parameters have to be set?

You have to setup the UART. With CCS you can use the #use rs232 directive. See the manual for reference. To have the interrupt "fire", you need to enable the receive interrupt and enable global interrupts. Take a look at "EX_SISR.C" in your examples directory. It shows how to do what you want. Also, this board has a search feature that you can use to find the information. Serial communications have been discussed quite a few times here. There should be many examples. You can search for "ttelmah" and the author. He has posted numerous examples here.
