For this pda, apparently, making a serial cable is very simple. No
max232 or something is required, you just have to connect the right
pins from the connector to the serial port plug (GND, RX and TX).
Note however, that usb networking seem to work already, only no ip
address is given to the usb0 device. I'll try to get usb networking up
and running as soon as possible (maybe even today), so a serial cable
isn't necesarry anymore (if I can find a way to login through usb).

These are the pinouts from the pda connector:
Pin1 GND
Pin2 USB0_N-
Pin3 USB0_P+-
Pin4 GND
Pin5 USB_CRADLE_DET
Pin6 RXD
Pin7 CTS#
Pin8 DSR#
Pin9 DCD#
Pin10 TXD
Pin11 RTS#
Pin12 DTR#
Pin13 GND
Pin14 GND
Pin15 NC
Pin16 NC
Pin17 NC
Pin18 VCC_P+
Pin19 VCC_P+
Pin20 VCC_P+
Pin21 VCC_P+
Pin22 VCC_P+

These are the pins you need:
Pin6 RXD
Pin10 TXD
Pin13 GND

They just go to the Rx, Tx and GND pins of the serial interface (see
http://www.lammertbies.nl/comm/cable/RS-232.html)

To find out which pin is which on the pda connector, I used the following:
There are two rows of pins on the connector. Most of the GND pins are
soldered together. That's how I found out (using the above pinout)
that one row is the even numbers, and the other row the odd numbers
(use the pinout to find out which is which).
