As for a cable to get to connnect to your modem I'd get this cable: http://www.serialio.com/products/ada...rial_RS232.htm It is already wired correctly for GPS and modem devices (connects to sync port).

Technically, you are correct. Functionally, the X5 supports USB standards, not RS232 standards, so while technically correct that the X5 has serial, it is unusable by "normal" RS232 means. The Sipex chip in the cable creates RS232 standard signals from the non-standard RS232-like signals present on the Axim and vice-versa. The cable you referred to does the same thing, only probably more flexibly because of the implementation.
