How implement Serial Mark/Space parity in RCM3720?

Question

Hi, there is possible handle Mark/Space parity for RS232.LIB using RCM3720?

this is the current paramenters:
PARAMETER1: A bit mask for selecting parity mode
PARAM_EPARITY 0x01
PARAM_OPARITY 0x02
PARAM_2STOP 0x03
PARAM_NOPARITY 0x00

Is it possible implement:
PARAM_MPARITY 0x04
PARAM_MPARITY 0x05

in RS232.LIB
void serXparity(int state);

Answer 1

Mark and space parity are supported directly in the serial hardware of the Rabbit 4000, 5000 and 6000, but not in earlier products.

You would need to modify the library yourself to add software support for those modes.
