Description Alex 2012-11-08 13:48:12 EST
Hi,

While experimenting with Mono on Windows I have run across an issue in
SerialPort.DiscardInBuffer and SerialPort.DiscardOutBuffer methods. I checked
the source code of WinSerialStream.cs (Mono 2.11.4) and found that both methods
use costant value PurgeRxClear while DiscardOutBuffer should be using
PurgeTxClear instead.

Apart from that PurgeRxClear and PurgeTxClear are defined wrongly as follows

const uint PurgeRxClear = 0x0004;
const uint PurgeTxClear = 0x0008;

while according to MSDN they should be

const uint PurgeRxClear = 0x0008;
const uint PurgeTxClear = 0x0004;

Please correct this issue in WinSerialStream.cs because now it is only possible
to clear the Tx buffer of the serial port. Also interoperabilty with .NET is
broken due to this issue.
