[App_rpt-users] Duplex=? Function in usbradio.con fan simpleusb.conf

I see the list of options for duplex= in rpt.conf, and the fact it is not the same function as used in usbradio.conf and simpleusb.conf, for which I am unable to locate a definition. These USB config files always has duplex=1. ; full-duplex. Are there other options, e.g. Half-duplex? Thanks, Bob kk6ecm Sent from iPad
