跟各位大大求教，小弟爬文找到這個連結(http://forum.xda-developers.com/archive/index.php/t-469718.html) 教導如何在wm6環境執行HP 2007釋出IPAQ藍芽鍵盤WM5的更新driver. 小弟的CHT9100已韌體升級WM6但是照步驟操作來沒是辦法仍然出現'Couldn't open port COM1:.rc=55"字樣，猜測是CHT9100上的COM1被紅外線佔去了，而HP IPAQ藍芽鍵盤的driver又非指定要把藍芽鍵盤設在COM 1不可，請教各位大大如果有類似的經驗是否能給予一些指導，感激不盡。
小弟操作的步驟如上述鏈結網站所述:
- download IPAQKB.exe into storage card
- download HP update 2.0.0.8
- used activesync to update wm6.1 with update 2.0.0.8
- download .NET framework 3.5 compact from (http://www.microsoft.com/Downloadsdetails.aspx?familyid=E3821449-3C6B-42F1-9FD9-0041345B3385&displaylang=en)
- open active sync and then run .NET application but make sure you chose 'custom' installation and put destination as :C\Mobile Device
- use bluetooth programme (start>settings>connections>bluetooth) to find foldable keyboard and tick serial port and also set COM 1 plus untick secure connection in the 'COM port section'
- run IPAQKB and select COM 1
- run foladable keyboard on in Programmes of wm6.1
- tick enalbe keyboard and thats it
