flush the serial buffer

I want to flush the serial buffer before I read from it (monitor it for the next transmission). Is this possible?

If you initialize and configure the serial device with tcsetattr() you can flush the serial buffer by setting the new tio with the TCSAFLUSH Parameter:

Code:

tcsetattr(fileDescriptor, TCSAFLUSH, &myNewTTYoptions);

See POSIX Serial Programming Guide for details.

PS: I made this tardy replay, since this post shows up as result number one while googeling for "flush serial buffer".
