Has anyone successful used synaser on a Mac (Lion)? In Connect it calls Flush
which always fails with "Not a Typewriter" which mean ioctl has invalid
parameters.
{$IFNDEF MSWINDOWS}
procedure TBlockSerial.Purge;
begin
{$IFNDEF FPC}
SerialCheck(ioctl(FHandle, TCFLSH, TCIOFLUSH));
{$ELSE}
{$IFDEF DARWIN}
SerialCheck(ioctl(FHandle, TCIOFLUSH, TCIOFLUSH)); <<<< Fails
{$ELSE}
SerialCheck(fpioctl(FHandle, TCFLSH, Pointer(PtrInt(TCIOFLUSH))));
{$ENDIF}
{$ENDIF}
FBuffer := '';
ExceptCheck;
end;
{$ELSE}
…..
I then tried this:
{$IFNDEF MSWINDOWS}
procedure TBlockSerial.Purge;
var
status: Integer;
begin
{$IFNDEF FPC}
SerialCheck(ioctl(FHandle, TCFLSH, TCIOFLUSH));
{$ELSE}
{$IFDEF DARWIN}
Status := 3;
SerialCheck(fpioctl(FHandle, TCIOFLUSH, @Status));
{$ELSE}
SerialCheck(fpioctl(FHandle, TCFLSH, Pointer(PtrInt(TCIOFLUSH))));
{$ENDIF}
{$ENDIF}
FBuffer := '';
ExceptCheck;
end;
{$ELSE}
….
Same results.
I have seen this:

***************
Does anyone have a simple example that works on a Mac?
I also tried to follow this example to connect and make the ioctl call to flush
and it fails as well……

I have spent all week googling/searching/experimenting and I am at a loss. I
also have asked on the Lazarus forum with no response….

I am desperate for help!
Thanks,
