PowerPC serial ports SMC and SCC

Has anyone here have expericne on the serial ports in the PowerQuick communications processors for RS-232 communications ? Those ICs are based on PowerPC architechture. The serial ports are wired to SMC and SCC controller parts of the IC in the board I use.

Basicly those ports work OK, but there are some problems when I try to use parity and 8 databits (I know 8 databits plus parity is a little bit rately used configuration, but that's what I have to use on the application). When I set the port to this mode, I get 8 databits out, but the parity is missing. I have verified this with line analyzer.

Has anyone ever tested that this should work ? Accordign the datasheet I understand that that both

8 databits and parity with it shoudl be supported by hardware. I have taken some look at the source of the serial port driver. It seems that the driver at leas tries to handle the data bits and parity settings right. The Linux kernel version I use is 2.6.12.3

Some info taken from stty -a -F /dev/ttyCPM1 command output:

parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts

According to this the line should be 8 databits and parity enabled.

Answers preferably to this newsgroup...
