Don't rush to actually order this one just yet! I think I made the holes too small for the through-hole connector. I forgot I was supposed to check the actual connector before finishing up.

Brian, that looks to be a great solution actually!  I may indeed have Oshpark build me one.

Yes it does require USB power and I've been trying to figure out how to supply that by alternate means.  I believe the WiModem232 with OLED would draw way too much current to power from a BCR port though.  Maybe a battery solution like you suggest is the right way to go.

    Looking at the wimodem...
    how about this?

    Untested since I just drew it up now. It acts as a male-male
    gender-changer for the rs232 pins, connecting pin2 to pn2, 3 to 3 etc,
    for pins 1,2,3,4,5,6,7,8,20,22

    The WiModem stands up instead of projecting out of the back, and the
    light and oled faces the user.

    Seems power is awkward for the WiModem though. If it needs a usb power
    source, then standing up like this you'd really want a right-angle usb
    cord. Myself, I would probably hack on a lipo battery and usb charger
    module or get power from the system bus or barcode ports on the M100 or
    something.
