Hi friends,

     I have developed a FPM to control the RS-232 port of the SmartServer. I have worked with 9600 baudios and I can change the speed to 19200 baudios without problems using the function rs232_ioctl (). I can send and receive information without problems and monitor the data using an oscilloscope. My problem appear because I want to use even parity. I enable this option using the function rs232_ioctl () and the command and data IOCTL_PARITY and PARENB but when I send any information the parity bit doesn´t appear. The source code is the next:

rs232_ioctl(_rs232_fd,IOCTL_BAUDRATE,19200);

 Hi Alejandro,

to set parity, use the following function (See page 217 ióf the Programmability Tools User's Guide):
rs232_ioctl(fd, IOCTL_SIO_HW_OPTS_SET, (options | PARENB | PARODD));

I recommend to update to the new Service Pack 2 because there is a RS232 fix mentioned in the Readme. 

Hi Chelo,

     I have configured my serial port (computer) with 9600 baudios, 8 bits of data, without parity and one bit stop.

     If I open the with:

             _rs232_fd = rs232_open(9600);

     the read and write is properly with rs232_read () and rs232_write functions().

     Now I configure my serial port (computer) with 9600 baudios, 8 bits of data, odd parity and one bit stop.

     In this case I use the next configuration:

          _rs232_fd = rs232_open(9600);

          int options = rs232_ioctl(_rs232_fd,IOCTL_SIO_HW_OPTS_GET, 0);
