Thank you very much for patches. This code uses Linux specific extensions which are included in new only kernels. It allows to access some additional low level serial port settings using IOCTLs/functions defined in <linux/termios.h> and <linux/serial.h>. So far I haven't use it due to rather pure portability and because I was to lazy to add to our make system autodetection for Linux version and header files. Anyhow I'll think yet about adding it and also requested by Mindaugas COM status line waiting. Again thank you very much for you help and fixing my typo in CLOCAL flag. best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
