    Has anyone tried the 2nd serial port on a V2.2 yet?

    I have the 1st serial port working, but can't seem to get the 2nd one to work.

    To validate my testing, I've even isolated just the TX line from the WRT, opened up a terminal

    cat /etc/hosts > /dev/tts/0

    Out puts correctly.

    Moved the TX line and the SGND to the pin that should be tts/1

    Same test, and nothing.

    I went and measured all the pins, and tried all the 3.3V lines and still nothing.

    Any thoughts or suggestions?

    I've also tried all the lines (TX,RX, SGND). tts/0 matched the V2's pin out. tts/1 seems like it should from what I measured.
