Serial2.dll (unlike the older SerialDevice.dll) is just a wrapper above .Net SerialPort class.
The problems you encounter with this device are not specific to Basic4ppc.
We are currently working on the next version which has some very important new features.
A wrapper to the GPS Intermediate Driver is also planned but as I wrote it will only be available afterward.
We do have a "100% satisfaction or money back guarantee" policy.
