wine users - Aug 2008 - Com Port ( USB) not working...Natiive Comport does work

I have followed this post

http://forum.winehq.org/viewtopic.php?t=1131&highlight=usb+serial+port

but am having no luck in getting my XP programs to use the com port...

The programs just dont seem to be able to use the port..

When I use my Linux terminal program the port works fine...
 I dont get an error saying that Com1 is not available...

Would like some help as I have a heap of application specifice programs for
thing like PABX's etc that I want to use under wine..
