I'm trying to connect to the gumstix console via this serial adapter http://www.robot-electronics.co.uk/htm/usb_iss_tech.htm and the ffuart interface provided by the robostix. I connected the GND pins, Rx of FFUART with Tx of the serial connector and vice verca... The power is supplied by the robostix. For the settings in hyperterminal I use those settings http://docwiki.gumstix.org/images/e/ee/HyperTerm_3.JPG. The terminal doesn't show anything. Somebody with an idea?
