[arm-allstar] rx_cosflap

[David McGough]

Alessio,

The setting you're wanting is rxondelay, configured in the simpleusb.conf 
file.  The easiest way to adjust this is via the simpleusb-tune-menu 
program, option M. This will allow you to adjust the parameter in 
real-time.

Each positive number step represents 20 milliseconds of delay 
applied every time the COS becomes active.

If you use a negative number, the delay is applied ONLY immediately after
PTT unkeys. This stops TX-RX ping-ponging, without applying the delay when 
the link is idle and a user just keys the system up.
