Volkslogger to Ipaq connection

HI,

I am using a Volkslogger to drive an Ipaq 3950 running
Mobile CU. However, as yet I have been unable to
get them to communicate, I would appreciate it if anyone
could suggest the correct settings to use. I have
tried setting MCU to auto detect with no luck and also
tried telling it there is a volkslogger providing the
signal but once again with no luck. I have also tried
changing all of the GPS sentences which the volkslogger
can output in, with no luck.

When I try to use XC soar software the Ipaq says the
serial port is allready in use (which it isnt) so maybe
this is part of the problem. If anyone has any ideas
on this subject I would be most grateful! Also, has
anyone had any experience of the cable/power converter
interfering on the radio and if so how did you shield
it?

Thanks in advance

Mark
