With my latest 302, a USB cable (type A to A) was provided. I am not
at home to meter it to see if it's a turn-around ("null modem" or
"crossover") type. I tried to use it once and failed, couldn't be
bothered. Use requires removing the glider's canopy, switching the 302
port from serial to USB, and connecting the USB cable. Much easier to
continue transfers with the serial cable to the PDA.
