Is it possible to reduce simplex nodes hang time to zero?

[Buhalo]

Unfortunately by default simplex nodes have annoying extra hang time even if hangtime is set to 0. Is there some tweak (app_rpt.c?) to reduce it to 0 so link would be able to dekey immediately when input source dekeys?

Try duplex=0 as documented on our Wiki.

In this mode local simplex node will not play courtesy tone in respond to mobile dekey.
Years ago i did some changes in app_rpt.c to fix remote node extra tail (~2 s) which appears even if hangtime in rpt.conf set to minimum. Just trying to find the lines.

Got it.
app_rpt.conf
[wait-times]
linkunkeywait = 0
When linkunkeywait is set to 0, link unkey still has some tail.
It seems that line 3905 of app_rpt.c prevents linknkeywait to be lower than 500 ms so i’ve changed.

interval = retrieve_astcfgint(myrpt,wait_times_save, “linkunkeywait”,500,5000,1000);
to
interval = retrieve_astcfgint(myrpt,wait_times_save, “linkunkeywait”,50,5000,1000);
