LazSynaSer on OSX 10.13 (High Sierra)

[JimKueneman]

Transitioning over from Synapse to Indy and needed a ComPort component so I grabbed LazSynaSer.  I can not get it to connect to anything with the changes that were made in the Purge method.  If I change it back to what SynaSer did it works.  During the Purge call I get "This is not a Typewriter" error code.

I pulled the version of LazSynaSer from the GitHub repository a few days ago and using Lazarus 2.2.4.

Code: Pascal  [Select][+][-]

1. {$IFDEF DARWIN}   // JDK
2. function real_tcflush(fd,qsel: cint): cint; cdecl; external name 'tcflush';
3.  
4. function TCFlush(fd,qsel:cint):cint;  {$ifdef VER2_0}inline;{$endif}
5. begin
6.   TCFlush:=real_tcflush(fd,qsel);
7. end;
8. {$ENDIF}
9.  
10. {$IFNDEF MSWINDOWS}
11. procedure TBlockSerial.Purge;
12. begin
13.   {$IFNDEF FPC}
14.   SerialCheck(ioctl(FHandle, TCFLSH, TCIOFLUSH));
15.   {$ELSE}
16.     {$IFDEF DARWIN}
17.     SerialCheck(TCFlush(FHandle, TCIOFLUSH));                               // JDK
18.   //  SerialCheck(fpioctl(FHandle, TCIOflush, Pointer(PtrInt(TCIOFLUSH))));
19.     {$ELSE}
20.     SerialCheck(fpioctl(FHandle, TCFLSH, Pointer(PtrInt(TCIOFLUSH))));
21.     {$ENDIF}
22.   {$ENDIF}
23.   FBuffer := '';
24.   ExceptCheck;
25. end;
26. {$ELSE}
27.  
28. Thoughts?

Hello,
last versions of synaser.pas and lazsynaser.pas use the same code for purge (except for freeBSD that lazserial doen't manage)
I have no problem on MAC OS catalina 10.15 using two USB serial ports.
Friendly, J.P

Ok thanks.  I would get that error on anything I tried to open including the Bluetooth cu and tty versions.  Do you know the reason it was changed?  Is there something concerning about the old way?

Jim
