I have an HP 6315 (6300 Series) and have installed GPS Gate. I am having trouble setting the "output" part of GPS gate. Under virtual port, I am only able to send to "com 0", as all the other ports are "occupied". The problem is my GPS software (iGuidiance) cannot select "com 0" (ie the drop down menu does not have "com 0". I have no problem in getting GPS gate's tray icon to turn green but can't set output to "com 0".
