Softick PPP - Network HotSync with Palm OS 5 Devices

Back to main product page

The problem

Unfortunately, during porting HotSync application to the Palm OS 5 ARM platform PalmSource forgets to swap bytes in Primary PC Address. That's why network hotsync takes too much time or just cannot be performed.

Solution

To address this very common problem Softick PPP has special NAT option which corrects broken IP addresses in HotSync UDP packets. To activate this feature open Softick PPP configuration dialog, select NAT page and check "Correct UDP header to workaround Palm OS 5 HotSync bug".

If you aren't sure whether your PDA has this bug enable Softick PPP packet sniffer, try to perform network HotSync and analyze packet log using WinDump program. If your HotSync is broken you will see the network packets (Primary PC address was 192.168.0.1)
