Question


How to Improve Performance When Transferring Larger Files over Serial ActiveSync?

Facts


MC90XX running Windows Mobile 2003 and CE .NET 4.2

Answer


MC90XX becomes sluggish while transferring large files over serial ActiveSync.

Modify and save the registry key specific for these settings.

  1. If the serial port is used primarily for serial ActiveSync and not for communicating with any external device, the following registry key may be changed to improve performance:
    • HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial1]
    • "RxTrigger"=dword:8 ;    Default value is 1
  2. Connect to the MC90XX through ActiveSync.
  3. Copy the two lines above into a .reg file, place the .reg file into the \Platform folder.
  4. Cold boot the MC90XX for the registry key to take effect.
