A buffer for receiving messages with flash memory?

Question

In Win32 C, is there an API call to reset (reset) the contents of the COM port receive buffer? I could only find functions for flushing transfer buffers.

Answer 1

`PurgeComm () ' can discard all characters in both or both of the Tx and Rx buffers and abort any pending read and / or write operations on the port. To do everything for the port, say something like:

PurgeComm(hPort, PURGE_RXABORT|PURGE_TXABORT|PURGE_RXCLEAR|PURGE_TXCLEAR) 

You can also make sure that you have processed or explicitly ignored any pending errors on the port, possibly with ClearCommError().
