Can one use fnFlush(..., FLUSH_TX) on ontput buffers?

[syakovlev]

At first glance it looks OK, but has anyone positive experience of doing so?
Thx.

Hi

Ensure that the following define is set in config.h - this will activate the flush support
    #define SUPPORT_FLUSH                                                // support rx flush

Usage is:
    fnFlush(SerialPortID, FLUSH_TX); // flush output buffer of serial interface
    fnFlush(SerialPortID, FLUSH_RX); // flush input buffer of serial interface

Note that
    fnFlush(SerialPortID, (FLUSH_RX | FLUSH_TX));
is not valid - it will only flush the Tx buffer (i.e. one call for each buffer necessary).
