Windows CE 2.0 users with a mobile phone equipped with a Infrared port often have trouble connecting their Handheld and phone together. The HPC:Factor Modem driver is a Generic driver and in tests we have had good success rates at connecting phones from different manufacturers.
Driver version 1.0.0.03 is written specifically for Windows CE 2.0; multiprocessor, however should work with newer versions if required. As ever we would very much appreciate user feedback on successes and failures with this driver.
