You may try to build serial cable yourself. I used cable from old serial
mouse. Even connector from the mouse side fits to OGO serial port. I
had only change location of wires. Here is description of OGO serial
port, I found on Internet.

How to make a serial port cable to connect a HP OmniGo 100 (or some
other HP laptops) to your PC for file transfer.

1. Obtain 2mm connector. The serial port connector uses pins spaced
2mm apart, and is *not* compatible with a normal ribbon cable
connector. Best source for the connector and pins is Digi-Key
(1-800-DIGIKEY)

Digi-key connector, part#s

part# H2004-ND Hirose Electric Co., A3B series 10-pin dual-row, 2mm
connector (HP 100/200LX)
part# H9999-ND Hirose Electric Co., socket terminals, quantity 100

2. Make a cable with the above connector on one end and a female DB-9
connector for the PC on the other end. The crimp pins on the 2mm
connectors are really tricky to attach without the right crimping
tool, but it can be done with small needle nose pliers and some
care.

Here's the pin-out for the serial port, looking at the port from
outside
the product (OmniGo 100):
