serCheckParity

int serCheckParity( char rx_byte, char parity );

Description

This function is different from the other serial routines in that it does not specify a particular serial port. This function takes any 8-bit character and tests it for correct parity. It will return true if the parity of rx_byte matches the parity specified. This function is useful for checking individual characters when using a 7-bit data protocol.

Parameters

rx_byte

The 8 bit character being tested for parity.

parity

The character `O' for odd parity, or the character `E' for even parity.

Return value

1: Parity of the byte being tested matches the parity supplied as an argument.
0: Parity of the byte does not match.

Library

RS232.LIB
