Unfortunately, the only person who really understands how soundmodem
works is the author, Thomas Sailer, and I have never "seen" him on any
mailing list. Having said that, I have been using soundmodem from
source for quite a while without any problems so I did a cursory search
for TIOCSETD and found this:
/* set the line discipline */
if (ioctl(master, TIOCSETD, &disc) == -1)
logerr(MLOG_FATAL, "ioctl: TIOCSETD");
ioctl() calls set kernel driver parameters. I'm not sure what the
comment "set the line descipline" means but it seems to have something
to do with Linux virtual terminals. If you find a document annotating
all the possibilities of Linux ioctl() calls, please send me copy.
