The support is in the 2.6 kernel (though not in 2.4 yet) and it should
work.  On the kernel side, look for I_IXON in drivers/net/ppp_async.c.
In pppd, the `crtscts' variable is set to -2 for xonxoff, and
set_up_tty() in sys-linux.c then sets the IXON and IXOFF flags.

If it isn't working, that's a bug and we should fix it.  Running pppd
under strace to check that it is actually setting IXON and IXOFF would
be a start.
