This means the os-x/FreeBSD/OpenBSD Termios is different size and  
structure that your Linux version,
sizeOfSTArrayFromCPrimitive gets the size of the bytearray that is  
being passed in. This means the
SerialPortTermios class is not setting the right size of the bytearray.

See the class comments in SerialPortTermios and SerialPortTermiosOSX  
class>>stuctureSize

See
SerialPortExtended>defaultExtendedSession
to decide how to instantiate your custom  extended session class.

Also see
SerialPortExtendedSessionUnix>>defaultTermiosClass

This is the BSD structure
struct termios {
         tcflag_t        c_iflag;        /* input flags */
         tcflag_t        c_oflag;        /* output flags */
         tcflag_t        c_cflag;        /* control flags */
         tcflag_t        c_lflag;        /* local flags */
         cc_t            c_cc[NCCS];     /* control chars */
         speed_t         c_ispeed;       /* input speed */
         speed_t         c_ospeed;       /* output speed */
};

see
www.opengroup.org/onlinepubs/ 007908799/xsh/termios.h.html
& of course you  need to understand the termios structure your unix  
system is using.
