No. As I mentioned, that is meaningless.

There are various commands that show the status at various levels:

lsmod | grep ^wctdm24xxp
dahdi_hardware | grep 'wctdm24xxp\+'
dahdi_span_assignments list
lsdahdi
asterisk -rx 'pri show spans'

What exactly do you consider as "status of dahdi"?

git log #?

The tarball has no changelog and thus it is not packaged. Sorry.

So it is no longer possible to make changes on dahdi parameters
without rebooting the machine ?

I think in the early days it was possible something like this:

make a change in /etc/dahdi/system.conf
asterisk -rx "module unload chan_dahdi.so"
service dahdi stop
service dahdi start
asterisk -rx "module load chan_dahdi.so"

Regards

Hans

There should be no need for a reboot. Long live your system.

What kind of change? Technically it would only take running 'dahdi_cfg'
to apply that change. However that may not be enough. Depending on the
specific change.

It only got faster. No need to deconfigure anything in Asterisk (This
happens on its own. At least on Asterisk >= 13). No need to unload and
re-load any modules (And why would you? Just to run dahdi_cfg?).

But anyway, if merely running dahdi_cfg is not enough, try:

  dahdi_span_assignment remove
  dahdi_span_assignment add # or: auto

This should also configure DAHDI and register spans with Asterisk
(again: >= 13). If there are still problems with asterisk:

  asterisk -rx "dahdi restart"
