    Hello,
            i'm trying to use the soundmodem-0.6 with linux kernel 2.4.16
    and PTT with parport.
    I'm getting the following error from kernel log:

            ppdev0: claim the port first

    and the following output from soundmodem:

    sbin/soundmodem
    sm[3171]: Device "/dev/parport0" neither parport nor serport
    sm[3171]: cannot start PTT output

            After a quick look at soundcard/ptt.c

    i changed line 90 from

    } else if (!ioctl(fd, PPRDATA, &x)) {

    to

    } else if ((!ioctl(fd,PPCLAIM))&&(!ioctl(fd, PPRDATA, &x))) {

    and the errors no longer occur.

                            Cheers,
                                            Nuno Sucena Almeida
