RX(/TX?)something delay

Is there a setting in ASL3 that locks out PTT (me keying the mic) after COS drops (my node TXing)…? Can’t grab control for up to 5 seconds; this is the 2nd project where I’m getting this behavior and I’m stumpted. This is a radioless/RF-less node; Pi3b and a modified generic CM108 FOB. Otherwise, everything works properly.
I have another ASL3 installation (Marshall’s Duplex HSRadiospot) that works fine and doesn’t do it. Clearly something I’m missing…

EDIT: Sorry, simpleusb

If it isn’t already, set your radioless node to duplex=3.

Duplex = 3 and linktolink = yes has solved the issue. (Thanks)
Now to revisit the identical problem I was having trying to get an AIOC board w/ASL3+simpleusb to work…
