Concerning speakup_apollo.c, it seems its only use of outb is to control the modem RTS line. To support that, yet another step will be: - introduce spk_serial_tiocmset(unsigned int set, unsigned int clear), which does: int old = inb(speakup_info.port_tts + UART_MCR); outb((old & ~clear) | set, speakup_info.port_tts + UART_MCR); - introduce spk_ttyio_tiocmset(unsigned int set, unsigned int clear), which does: speakup_tty->ops->tiocmset(speakup_tty, set, clear); and make them a tiocmset method of synths. and then in speakup_apollo.c, instead of outb(UART_MCR_DTR, speakup_info.port_tts + UART_MCR); outb(UART_MCR_DTR | UART_MCR_RTS, speakup_info.port_tts + UART_MCR); rather use synth->tiocmset(0, UART_MCR_RTS); synth->tiocmset(UART_MCR_RTS, 0); Samuel _______________________________________________ Speakup mailing list Speakup@xxxxxxxxxxxxxxxxx http://linux-speakup.org/cgi-bin/mailman/listinfo/speakup
