problem initializing XBee Series 1
I have an XBee Series 1 hooked to a Parallax USB adaptor (both from Adafruit). The adaptor is connected to the laptop via USB. The green and yellow LEDs are on. The red LED is blinking.
I am using CoolTerm to configure. It says I am connected, but typing +++ doesn't get an OK back. I tried jumping Din and Dout, so there shouldn't be a problem w/ tx/rx. When I type +++ and hit enter, the red LED flashes briefly, so it looks like the adapter is receiving the transmission, but nothing else happens.
How should I troubleshoot from here?
