Trying to convert a usbradio box to simpleusb. But thew usbradio setup uses pins on the parallel port for PTT and COS in. Tried this with simpleusb and no-go. Looked in the most recent source for simpleusb.c and I see reference to the port: #define PP_MASK 0xbffc #define PP_PORT "/dev/parport0" #define PP_IOPORT 0x378 But in the configs section of the source I see: carrierfrom = usb ;no,usb,usbinvert which does not show pp or ppinvert as choices. So...am I chasing my tail? If simpleusb cannot work with pport I'll leave it as-is. commands radio, rpt no longer there. Channeltypes shows simpleusb, not radio. Then I also remember there should be a file in /etc/asterisk (I think) that tells it what kind of channel it is, but I am having severe senior moment-itis.. Can anyone un confuse me? And yes, latest sources are installed. George J Csahanin W2DB Cedar Park, TX 512-401-2630 401-338-0568 cel
