hi,
while configuring the serial port, the character size is set as
Code:
    options.c_cflag &= ~CSIZE; /* Mask the character size bits */
    options.c_cflag |= CS8;    /* Select 8 data bits */
source: Serial Programming Guide for POSIX Operating Systems - Michael R Sweet
if i want to take more bits than 8, what do i use?

thanks.
