Okash, this may be related with the serial port layer buffering data. I realize that we haven't made the synth_flush functions call the flush_buffer tty ops. We need to do so, otherwise even if we send the clear character, that's only after the processing of pending data. So in the synth_flush functions, one needs to first call flush_buffer() and then send the clear character. Yes, flush_buffer is yet another method to be added to the spk_io_ops structure. In the serialio case, you can just let it do nothing. One could want to flush the UART 16550 buffer but that's not the point of your patch anyway :) Samuel _______________________________________________ Speakup mailing list Speakup@xxxxxxxxxxxxxxxxx http://linux-speakup.org/cgi-bin/mailman/listinfo/speakup
