"Can't open COMM port" errors

Hi all,

I have a dell axim X51V and the Haicom HI303III CF gps receiver.

On the whole they're working great except for one annoying issue. I've searched the forums and found various issues that sound similar but most seem to be the opposite to what I find. Others seem to lose their CF/BT gps devices after a reset. I'm having the reverse...

For _ONE_ time after power is turned on (from standby, soft reset or hard reset conditions) I can use any of the gps applications to find my device correctly.

However, as soon as a close the comm port connection and try to reopen it I get a can't open the comm port error message and I can no longer talk to my gps.

I have to either remove the GPS and reinsert, or go into standby/back on my axim in order to be able to re-open the port.

It seems that the comm port is not being released fully when I close it - and the application either thinks the port is not there, or is already in use.

I have tried with the Wm5 managing my gps (sharing hte ports) and with it 'disabled' - but it seems to make little difference.

Can anyone shed some light on why I can't use my comm ports twice without a 'reset'? This is the only niggle I have with this pda... :(
