You can use a USB to serial adapter to connect your laptop to the gumstix tweener board. I use this one from staples: Belkin USB to Serial PDA Adapter, but any USB to serial adapter should work. Just connect the serial cable sold by Gumstix between the adapter and the tweener.

I would like to use my Thinkpad (without the RS232 port - on the ultrabase) to connect to the tweener expansion board.

Do you know where I could find the wiring schema of such an RS232 cable  ?

    - on the laptop side - USB
    - on the gumstix side - Mini DIN 8

Thanks in advance for your answers,
Best regards,
