[arm-allstar] timer question

[Barry Buelow]

I'm working on a remote base UHF/HF.  Single RPi server with 2 nodes. 
UHF node is Duplex=1. HF Duplex =0. DTMFs are passed to a program via 
*6xxx which calls my intermediate program.

When I key UHF HT, the HF goes into Tx as desired.
However, if I key UHF HT and do DTMF, releasing UHF HT PTT does not 
result in dropping HF Tx. There is a LONG hangtime.

If I do the DTMF via the linux cmd line (asterisk -rx "rpt fun ....")  
it works as expected, no long hang time. I can view the extended PTT 
assertion using SimpleUSBtuneMenu. For unknown reasons, the UHF node 
decoding DTMF triggers a longer hangtime. I'm thinking this may be 
related to using the Autopatch function, but I'm not sure.

Suggestions?

Thanks in advance.
