void Posix_QextSerialPort::ungetChar ( char  c  )  [virtual]

This function is included to implement the full QIODevice interface, and currently has no purpose within this class. This function is meaningless on an unbuffered device and currently only prints a warning message to that effect.

Implements QextSerialBase.

      /*meaningless on unbuffered sequential device - return error and print a warning*/
