UART How do you change parity or data len within program?

[reynomj]

Hi

Can anyone help me? I am aiming to write a serial port analyzer and have been looking through the CCS C manual regarding changing the serial port data bits and parity within the program code? The only functions I found are listed below.

#use rs232 - Preprocessor no good for dynamically changing parameters within code?
setup_uart - only changes baud rate and stream.

Has anyone had any experience or example code of changing the parity or data bits within programs code?

There is a bigger problem than this....
The PIC, doesn't really support parity at all. The only support is via software, generating the extra bit if needed.
This is why it is not configurable 'on the fly', since code has to be added to provide the support. Some layouts are basically impossible (so for example, - 7bit, no parity, one stop, which the hardware cannot generate).
You can give yourself an even/odd parity software selectable, by either declaring two streams,and selecting the required one, which then results in both sets of code being generated, or simply selecting 9bits, no parity, and generating the parity bit yourself.
