Re: TCSBRK not implemented in linux compat
Hi, thanks. I think for now I can work around this although it would
be nice to have this implemented.
Regards,
Arjan

I think you could just make it call TIOCDRAIN directly. Unfortunately
that's not correct if the argument is 0, because then we have to call
TIOCSBRK and TIOCCBRK with a 250 msec interval. I guess adding some
kind
of printf() there should be good enough for now.
I can't look into it right now, because I have to get up at 6:15
tomorrow. Sorry! :-/

TCSBRK not implemented in linux compat
Hi,
While trying to get a linux binary running on FreeBSD I encountered
the following problem during serial port I/O.

0x5409 turns out to be TCSBRK, which is not implemented (yet?). Can
anyone give me some clues where / how to start implementing this? It

I believe you want to talk to Ed Schouten as this is a TTY thing..
I CCed him

While trying to get = a linux binary running on FreeBSD I encountered

Dec 1 22:22:34 soekris kernel: = linux: pid 7239 (linuxbinary): ioctl

It
seems like the linux way of handlin= g it is to call tcdrain(), but
I'm
not sure as to how this transla= tes to the FreeBSD compat layer.
It should probably be translated to= the same BSD call. What it does
is
drain the buffer then send the seria= l BREAK signal: a low-voltage
signal lasting
longer than the length of o= ne normal character. The other side can
detect this and generate
an inte= rrupt, which then may get translated to a signal (see the
stty parametersn= bsp;
ignbrk, brkint).
