[arm-allstar] removing squelch crash with the SA818

[Doug Langley]

I am trying to find a good way to remove the squelch crash when using 
SA818 based radios.
 From the research I have done, it looks like the two best ways to do 
this are by using DCS instead of PL, or by using the
Close Tail Tone Command
in the SA818 radio.
It doesn't appear as if the 818-prog script supports the

AT+SETTAIL=0
Would this be  something that would be easy to put in a future release, 
or, do you have any good suggestions of easy ways to send this command 
to the radio?
I would rather stay with PL, to not reprogram a bunch of radios, but, if 
DCS is better for some reason,I can go that route

Thanks as always for your help.
