Hi All, Is their any posix functions that let you know how many bytes in the receive buffer as can be done in ioctl? If not, is their a way to do it besides the ioctl and if their isn't, it is recommended to use ioctl with posix termios? Is it safe to say termios only alows access through read/write functions?
