Hulen, Remember, the radio is actually the software. All the hardware does is act as an RF modem.
PowerSDR (the REAL radio) does utilize serial ports. Open the Setup form & click on the "CAT Control" tab. There you can select the serial port to use for CAT control & a separate port (if desired) for PTT control. The manual does not "suggest anything unique for the 1500 with regard to CAT" because PowerSDR handles CAT the same way regardless of the type of radio. You are correct in that much of the FLEX-1500 manual is copied from earlier manuals. Again, that is because PowerSDR is used for all of the radios, & each manual repeats what is common. It only goes into specifics for each type of radio where hardware differences demand it. 73, Ray, K9DUR http://k9dur.info _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
