VSTATUS, VDISCARD etc.

[Yedidyah Bar-D. <di...@po...>]

Hello all,

I used to be a VMS sysadmin, and missed Ctrl-T (which outputs a status
line). I started to implement support for this for Linux, and sent
email to lkml and linux-serial, which got only one reply.
See <http://www.cs.tau.ac.il/~didi/ctrl-t> for my current patch,
which is probably not-too-bad (I use it on my home machine for
many months).
Today I saw (on Kernel-Threads) that this project (Linuxconsole) exists.

My questions:

1. Is this On-Topic here?

2. Is anyone interested? Is there a good chance that such features
will eventually get in? The current termios(3) says 8 times that
'something' is not supported under Linux. For completeness, I
might implement them all, in addition to anything that exists
elsewhere (e.g. *BSD) and someone wants.

3. Is it now a good time to start working on this now? Is the
new tty interface stable? I searched (briefly) the archives
for 'n_tty' and 'vstatus', and found nothing.

4. From the questions I asked in the mail to lkml, you see I
am far from being an experienced kernel programmer. With the
new architecture, will I need to be (especially locking issues),
or will it be taken care of in some other levels? Not that
I am afraid, but I realize there is no chance such patches
will be accepted by anyone if they make problems, since clearly
everyone can live well without them.

Thanks,
	Didi
