Any help / advice / comments most appreciated here!  

I've managed to put together a cable to connect the Ipaq to a Garmin GPS (one end Ipaq, other end Y split fits to Etrex and 60CS). Tried it with both GPSs but can't get a connect.  I've wired up pins 7 & 8 from the Ipaq (from http://pinouts.ru/PDA/ipaq_22p_pinout.shtml ) to the appropriate pins on the plugs Rx<-->Tx but without any joy.  Neither Wififofum, G7towinCE, nor Winfast Navigator can connect to a comm port: GPS set to NMEA and 4800. 

3 possibilities spring to mind:
 - I stuffed the cable wiring: possible, but it all checks okay on the meter
 - The 6365 is like the 6315 and doesn't have serial on pins 7&8: although it does apparently support an external kbd
 - there's a magic tweak required on the 6365 required to get a comm port enabled for use?

The error messages (serial port timeout, asyncinit error, etc) seem to indicate that the program can't see/initiate the Ipaq port rather than just no data coming through.  I've gone into Start/settings/System/iPAQ Keyboard and the keyboard and sound boxes are both blank, i.e. not enabled, but knowing this unit I don't really trust that it's been turned off!

Has anyone else got one of these little beasties talking with a GPS or any idea where I should start looking?

Thanks,
G.
