Perhaps I am missing something here. The Garmin cable to the PC is a simple
cable, no electronics in it. It should show continuity on each line/pin.
>From what others have posted the ASUS A620 has a ttl to RS232 converter in
it. I would not expect it to show continuity between pins. (And I would not
be surprised if you happen to check between pins on the same connector (eg.
between pins on the RS232 connector) that you have blown the converter
within the ASUS A620 cable. The convert is protected when power up, but
applying power to pins on it when it is not power up is a very bad thing to
do, generally.

Here in the States I would need both a null modem adapter and also a gender
changer. Most PocketPCs have two versions of a serial cable. One designed
for ActiveSyncing which would require both the gender changer and null modem
adapter from Radio Shack. The other type, would be to add a serial
peripheral to the PocketPC (Which is harder to come by, and in my experience
generally short say 6 inches or so) and will have the same 9 pin connector
as on your PC.
