wine users - Jan 2010 - Wintex 5.4 com port setup

Need to allocate USB0 to COM1 for Wintex 5.4 alarm software.
Ubuntu sees the alarm panel (on device manager) on the usb port, but the
software does'nt connect.
Wintex software setup gives the options of Com1 to Com16.
I have already tried:  
cd ~/.wine/dosdevices
ln -s /dev/ttyUSB0 ./com1
Still not working.
Any ideas?

Version wine ?  Biffvj 1.0.x versions of wine do have problems at times working
with usb serial ports.
