p910i serial ports

I'm having a spot of bother!!

I have a little application which connects via BT virtual com port to
a phone (tested with t610 and t39m) which reads the phonebook and then
looks for an incoming call... ok - no rocket science there but....

Trying to connect it to my p910i is impossible.

Thre only appears to be 1 BT serial port, whereas on the other phones
there were 2 - does this make a difference??

I could use other phones as a modem by connecting via the virtual BT
com port and it would accept all the standard AT commands - the p910i
WILL NOT!!!!! With IR and Cable, there;s the coice of determining if
the connection is PC Connect or Modem, but BT doesn't offer this. How
on earth do you connect via BT to a p910i to access the serial
ports???
